You don’t like r/The_Donald on Reddit?
I browse there a certain amount, although I don’t yet participate. It is exclusively pro-Trump, so they don’t get to do battle directly with the left, but some good stuff gets posted there (along with a fair amount of spammy stuff).
p.s. Welcome aboard on FR!
Thank you. I belonged to a large suspended pro-Trump group which were more “combative” against the left :)
