I'm not really sure what that article is saying, maybe "Placeholder / bingo card arguments make it hard to have a rational intellegent debate/conversation". Which is technically true, it does make it hard to have an intelligent conversation.
However, in the vast majority of conversations about topics like this, the debate is not intelligent. The same old tied tropes and clichés come out. Many different people have commented "But he's racist too!" (on a recent post about gender at a tech conference many people dismissed the author for being angry).
