SJWs don't have conservative thought.
SJWs don't care if men exist or not.
See but this article seems extremely concerned with whether men exist or not, since it talks about all the reasons why having a resource-costly feature such as biological love is actually beneficial from an evolutionary standpoint.
To me it sounds like you read the article's title and assumed it was some kind of radical feminist thing about why men are only good for their semen and jokes. But that's not the reality at all.
