Not for that comment, but for the pattern of breaking the guidelines. Note the words "repeatedly" and "plenty" in my comment above. If it had just been that one comment, we'd have either posted a warning or not done anything.
There's another factor too: when we have reason to believe that the person has done the same with previous accounts, we're more likely to ban instead of warn. It's all relative though.

I know it feels like the other side always gets a pass, but actually, when accounts with those views (or any views) are breaking the site guidelines repeatedly, we ban them too.
If you see some that we missed, links are welcome. We don't come close to seeing everything that gets posted here.
