Probably it would be easiest for all the pro-Trump people to put all the anti-Trump people on "ignore", and vice versa. Then neither side would get thumbed down, nor would we have to worry about actually having to explain or defend ourselves!
(Before I get voted down — it was a joke.)
I only have one person on "ignore"; cammie left before I got the chance to add him to the list. And while I have thumbed people down on a few occasions it was because their post was really bad
, what I consider personally insulting, overly hostile, or excessively crude. And I've thumbed up righties a few times when I see a high quality post.
