@engineer,
Nonsense Engineer! Do you consider that saying that an argument is "prejudiced" an ad-hominem argument? Of course it is not.
Criticizing someone's beliefs, or actions, or argument, logic are all part of disagreement and can be civil. I have been accused of "parroting" big pharmaceutical companies, or of failing to think independently in science. I don't feel personally attacked when someone disagrees with, or even attacks, my arguments or positions.
When someone attacks my logic, or my actions or even my motivation in an argument... these aren't personal attacks.
Personal attacks; calling someone a "moron" or a "Nazi" are different, they attack someone's character rather than their attack the character of the person or their actions.
If you tell me that as a White man I am failing to acknowledge the experiences of women or minorities... I might disagree with you, but it is not an ad hominem. For one thing, if I decide you are right, I can change this behavior. If I decide you are wrong, I can either debate the issue or let it slide. This is also a criticism on one position I am taking, it says nothing about the other positions I take or on my value as a human being. This is is fundamentally different then if you would ever call me a "moron" (which is an attack on basic character that I presumably couldn't do anything about).
People are now claiming "Baby, it's cold outside" is now offensive and as a result they are being removed from playlists on radio stations. This is something that I personal feel is ridiculous. I am not attacking the people.
I am criticizing the idea that this flirty song are is any way offensive an that songs from the 1950s should be judged by 2018 sensitivities. In my opinion this idea is ridiculous.
I am not attacking the people at all. I am attacking their politically correct behavior in this specific instance, and what I see as a trend in society. You can't have this discussion without criticizing politically correct attitudes.
