Every human is created equal. But then again - those who believe themselves above other humans and actively hate them and try to strip their freedom away (through race, money, etc) - those I do deem to be less than human, and below me and anyone wanting to live in peace.
The hateful will always have reasons to hate, they actively look for them in everything and base their lives completely on their misery, and their ability to spread it to others like a plague.
If you can't live in a world with people different from you, and you feel the need to harm them, maybe instead of killing them, it'd be easier to get rid of you instead.
