Who cares? Hate is part of being human and part of life, and people hate for many different reasons. Let them hate. As long as they're not trying to hurt innocent people, who cares?
Aw man, that's kinda mean. But I sort of get where you're coming from. A company owns exclusive rights to the .sucks TLD, so I guess in a way they're profiting off of hatred. I just don't really think it's that big of a deal. Like, if I'm angry at something I'm not gonna buy a domain for it... Especially since these are so expensive. Barely anyone buys domains. Seems like it's more tailored to marketing campaigns than anything.
