You're saying you could go look for hate speech and find it. That doesn't seem all that troubling to me. Don't go look for it, and you will find it much less frequently.
I'm saying that it is everywhere. Not "I could find some hatred in some submissions", but "I could find hatred in any submission".

Allowing the hate groups a home on reddit makes them feel comfortable. Deleting the hate group subreddits reduces their ability to silence others. It sends a message to both the haters and their targets that the hate is not welcome.
If it's a choice between censoring a bunch of evil bigots, and letting their uncensored speech censor the people they hate, I will pick censoring the bigots every time.
