A few thoughts on all the errors in this comment.

Maybe there are atheists who hate fairies, leprechauns, or unicorns.

According to the Bible, unicorns do or did exist. Are we allowed to hate them?

Wait, how can we hate a creature that farts rainbows? Maybe all atheists love unicorns!

Of course it is possible to hate something that does not exist. Hate is a subjective emotional feeling that you can apply to anything. You can hate orcs, or the Kree, or the way Mercury messes up your day when it goes retrograde, or Satan.

Can you love something that doesn’t exist? Ray Comfort loves a deity that doesn’t exist, so apparently it is possible to have strong emotional feelings for nonexistent entities.

Actually, most atheists don’t hate gods at all. We do hate the fact that con artists like Ray Comfort use religion to promote intolerance and ignorance, so it would be more accurate to say we hate religion (and not all atheists do that, either).
