This is what really infuriates me about radlibs. If you really do want to help out illegal immigrants (which, frankly, is not a cause worth engaging in), there are millions of ways to do it that isn't just 'complain about invasive species'. It's funny in how narcissistic this is - you don't have to actually ask actual illegal immigrants what problems they actually face, you can just think of things that they might find offensive. Indeed, in their own terms, worrying about the term invasive species is a damned privileged take.
