Right wing political spaces have a negative corrolation with female participation.

yeah, that's an interesting observation, which makes you wonder what is cause and what is consequence.

So if we accept your hypothesis, then we could also conclude that OP’s love interest is already involved in significanly right-wing spaces.

Yeah, that's a likely outcome i guess. Girl falls for "strong" men in the past, suddenly realizes they're all right-wing and potentially dangerous, suddenly tries to find a non-dangerous partner, or sth like that.
