There is (at least) one regular member here who has demonstrated to be fully onboard the Conservative hype train (and has on multiple occasions tried to excuse and/or tone down several of the authoritarian measures attempted by the GoP) who has not been banned, nor has there been any reason (as far as I'm aware, as I'm not a mod) for them to be banned in the first place. There are also (at least) 2 other regular members who, while I wouldn't describe them as Conservative, are definitely much more right-leaning than most other regulars here, and have been active in this subforum for quite a number of years.
You're implying that this subforum is an echo chamber, and it's anything but, though there have been a couple of low points over time. In my own observations, it's usually the expectation of actual discussion and holding people accountable for what they say that generally drives users away, rather than solely the difference in ideology. I personally don't think that's a bad thing, as it keeps the quality of discussion relatively high, and stops the site from potentially being a platform for people with legitimately dangerous ideals.
I live in West Florida. At the current moment, my state is attempting to infringe on the 1st Amendment Rights of an American company and its employees, and (up until recently) was attempting to re-draw its voting lines so that the one district of mostly black voters that's run by a Democrat would be split, which would give Republican votes much greater representation in this state. Keep in mind, even though Florida is considered a swing state, it's typically been a pretty solid safe heaven for Republican voters for quite some time. I'm also a Black person, work retail in a small independent store, and attempt to keep a keen eye on the political and educational happenings due to having friends and family that are/have been involved in local government and education.
With that, I think I can safely say I have an idea of what "real life republicans" are like here. Like
@Joey D said, while a lot of Republicans in this state don't necessarily support authoritarianism, a
very concerning number of them do, even though the majority of them are actually pretty nice people all things considered. Again, my state is being run by a man going after the constitutional rights of a lot of American workers because he didn't like what their CEO said about a recent education law (a law that in of itself infringes on others 1st Amendment rights, and at one point
was shaping up to infringe on peoples rights to privacy),
and a significant number of voters here are loving it. These people aren't "fringe," they're a significant percentage of the voting populace.
The Capitol attack is the reason
why voting is important. Abstaining from voting give people like the ones who attacked the Capitol (as well as the politicians who represent them) more room to secure their power. That day was just a taste of what could happen to this country if we let things go too far without accountability.
