i don't think she's even doing that. note this part:
They show more empathy IRL in spaces they’re recruiting in [emphasis mine]
it seems clear to me from her words that she doesn't like that this was her experience, that "leftists" have not been as willing to try to accommodate her while recruiting. and that shows part of why they've been effective in radicalizing people. as long as you're not against them (and you're not visibly not white or not hetero), they're willing to try to get you to be with them.
hence they are able to effectively radicalize ppl.
