though the rare antitheist can be this bad in exceptional cases.

May all that's unholy preserve us from a devout antitheist.

snipped for brevity

Antitheism doesn't do that.  I think that theism is a moral evil.  You'd wear out your trigger finger eradicating everyone who does or affirms moral evil, though, and you would at the end have to off yourself as well.

No, certainly not by itself. That said, I've met a very few people who were antitheists who did go down the militant shrieking path. Not pretty. Most antitheists are pretty chill though.
