Plenty of center-left liberals here, and a few but some sane center-right, who openly don't much care for actual leftists. The only genuinely unwelcome I've seen are MAGA trolls, which... good. But "centrist" can mean lots of things, some of which get slagged because they're just plain dumb.

Personally, I draw a distinction between moderates both left and right, who are very often good and thoughtful and have a coherent worldview, as opposed to self-described centrists, who tend to be offering insipid golden mean fallacy bothsides-ism of the sort that's just intellectually bankrupt.
