Fair, but if I would count every criticism as hate I'd drown in hate. It's worth- and pointless criticism, but is it hate? Block them, ignore them, let them live their shitty lives. Are downvotes hate? No, someone just tells me they don't share my opinion.

Edit: look, in not saying their opinion is good and valid and should be heard. They can eat a bag of rocks on a Friday. But giving them too much thought and emotional response just isn't the best for your own mental well-being, so just let them swallow their own negativity and ignore them.
