@maxdancona,
Olivier's point was that our moral sense should be used to judge ourselves; not others. I essentially agree with this but would restate it as:
our moral sense should be used to judge ourselves; far more than others, because I think there are legitimate reasons to make moral judgments about people. Of course this doesn't mean each of these judgments needs to be loudly pronounced in a large crowd or even just to the person being judged.
It seems to be, as well, that people tend to view judging other people as somehow wrong (even thought they do it all the time). Calling someone "judgmental" is not flattery. So I am wondering where this comes from. "Judge not lest ye be judged thyself" is a pretty often quoted line from the Bible and I suspect there must be other similar lines within it.My question is whether our Western aversion to judging others is a product of our Judeo-Christian origins or somehow more innate.
As for your points, I can't speak for anyone else, let alone all conservatives, but I don't believe liberals are inherently bigoted, and I don't believe conservatives are free of this sin. It's, unfortunately, far too easy to generalize when one is on one side of the river throwing rocks and feces at the tribe on the other side, but I try (and not too successfully) to avoid doing so about liberals, in part, because it annoys me when they do it about conservatives.
There are ideological (although perhaps partisan is a better choice of word) positions which can resonate with bigoted people, but that doesn't mean they are based on bigotry.
Controlling immigration is an example. A proponent of this need not be conservative or liberal, although it does tend more to be a position of the former. Reasonable and supportable arguments can be made, and have been made, for clamping down on illegal immigration that have nothing to do with bigotry. More than once I have discussed this with liberals who will acknowledged the validity of the underlying premise, but had differences with how it should be achieved. Folks who are bigoted towards Latinos are more than likely to be in favor of this position, but that doesn't make the position one of bigotry.
The impact of Christian fundamentalists on our society is another. Again you don't have to be a liberal or a conservative to find this problematic, but here liberals outnumber conservatives in believing it to be so. I happen to believe not only in evolution but that pseudo-science of any kind should not be taught to our children (referencing creationism is another matter) A great many liberals approach this from a reasonable and supportable position, but the fact remains that many also exhibit bigotry towards Christians.
If you have a character that allows for bigotry, it doesn't matter what your ideology is, you will find a way to express it. The common liberal refrain that all conservatives are not bigots (or racists) but all bigots are conservatives is simply, and demonstrably not true.
You are right that it is currently a societal problem that most (not all) conservatives think poorly of liberals in general and most (not all) liberals think poorly of conservatives in general. At the same time I have liberal family members and friends who I don't think poorly of because of their ideology, and the same is true in reverse. The problem, IMO, is that we live now in the
Age of The Internet and rather than it being a means to connect people from all around the world (as initially touted) it has become a means to reduce our personal interactions and drive us into echo chambers that reinforce positions that need to be challenged.
Of course self-reflection that leads to admitting prejudice, and bias and questioning, from time to time, all of your beliefs is a good thing, and I think a lot more people than we might imagine do this. Unfortunately I think that number is shrinking because life in an echo chamber (or bubble) makes it easy to avoid doing something that is essentially difficult.
Having said all of this, the person described in the OP, IMO, is fundamentally bigoted, regardless of her ideology, and not simply ignorant . It doesn't require anyone to call her out on it, although an attempt to discuss it with her might be helpful. It is a generally liberal position (particularly, but not exclusively, among young liberals) that it is a good thing to
call out bigots wherever they raise their ugly heads. Great in the abstract but first of all it's of little value, because if it ever was, it merely led to bigots going underground, and now, thank again to the Internet, bigots have their own echo chambers and have been empowered. Secondly and most importantly the justice warriors doing this have gone way, way overboard and see the most mundane and innocent comment or act as a sign of bigotry. They use what should be a righteous mechanism used sparingly when obviously appropriate as an ideological club for bullies. They are far more likely to create sympathy for bigots than condemnation outside of their bubble.
If Milo
Yannapopodoplous is truly a bigot (and I don't think he is anymore than the rest of us) their extreme reaction to him has empowered him, not silenced him. They forced his publisher to withdraw his book deal and so he self-published and is selling his book to great numbers who, if nothing else, don't want to see the mob trample free speech.
My view is that we each should focus primarily upon ourselves and reduce or eliminate whatever bigotry we have allowed ourselves. After that we should avoid associating with and in anyway supporting obvious bigots and if we are up to it we should try and persuade one or more of them why they are wrong to think as they do.
We do not (despite what the hyperbolic few in the forum would claim) live in a nation where there is a major political force fueled by bigotry. We are not in the same place Germans were during the rise of the Nazis. Should we ever be in such a place then my view on how to deal with bigots would change and expand.
