Not that specifically. I’m more concerned that for the one you convert, two go the other way. Obviously, it’s impossible to know the real number so it very well could be me being pessimistic and overcautious.

Yeah, it’s hard to define that one. Enter the paradox of tolerance (which is not a paradox, but I digress). Excluding them risks an echo chamber, welcoming them invites a general degradation of the space (see: literally every conservative space that devolves into rabid negativity). I think that it’s less about exclusion and more about a standard. Along the lines of “you can like Trump, but if you’re going to argue, do it in good faith or get out”. Stupid nuance, making things hard…
