I fully appreciate what you're saying. I will say this though, it's hard to want to have civil discourse with people who support politicians who actively are trying to strip my rights away and think I shouldn't exist. I know they themselves might not agree with that aspect of the politician but by continuing to vote for that person they are condoning what the politician is doing.
I'm not sure how fringe they are anymore. Look at the recent Bud Light and Target fiascos. I think the sentiment is larger than people thought
