Nice to meet you.
What percentage of this board is MAGA?
It's really tough to say. It's clearly disproportionately MAGA relative to the population of the United States. Well over half
voted for Trump repeatedly and it's up to you to say if that's enough to make you MAGA. Lots of people who've voted repeatedly for the guy specifically don't identify as MAGA, for what it's worth.
Of the active posters, I'd guess about 35% would be MAGA under any reasonable definition. 30% are left of center (or didn't vote for Trump) but we're outspoken and tend to descend like locusts into threads. We certainly seem to have a "defend the herd" mentality.
The other chunk is a bunch of people who've vote for Trump but "weren't happy about it" or find plenty to disagree with him on. That's the group of people that I can at least talk to.
My "side" does have two posters who jump to mind who are pretty close to trolls and several others who troll the MAGA trolls but are otherwise good posters.
There are significantly more garbage posters on the right, but I'm biased.
