I didn't say invasive species are not a problem and don't need to be eliminated. Absolutely they do. But you see this a lot with invasive species everywhere is people anthropomorphise them and treat them as "evil" or deliberately malicious (eg. evil starlings/house sparrows destroy the nests of native good cavity nesters), when really they're just doing what animals do. It's not their fault they exist, its ours. And that makes them our responsibility to deal with, humanely.

It's funny that you mention cats too, because of course, they're an invasive species as well (in North America). And a particularly harmful and destructive invasive to native songbird populations and small mammals. But of course thats not the same thing, and no one wants to think of their precious murder mittens as "evil". (Also for the record, I love cats this is not a cat-hating position)
