There’s a difference between conservatism and regressivism, and as you yourself keep saying, the Republicans you see on the internet (your source, apparently) are not just being conservative.

Which again, begs the question of why you think you’re qualified to claim that this is some “truth”.

And again, I’m completely sympathetic to the idea that uncritical hatred and demonising of “the other side” leads to uncritical and one-sided ideas of the “truth”.

What I think you’re missing is the nuance that someone can consider both sides and still consider that one side is indefensible. The disqualification of the modern Republican from being “good people” does not mean that someone has not carefully thought through their stand.

Now about how you react to bad people: you can give them a chance to be good - the benefit of the doubt that they may not actually be standing for everything that being a modern Republican involves. But like I said previously, it might be a good time for those people to re-evaluate whether they actually are Republicans (an archaic term that has no real meaning today beyond a party affiliation) or feel like maybe it’s time to recognise something has gone deeply wrong.
