Earlier quoted context omitted.
No, it isn't. Given that there was no blatantly illegal content involved, there are only two possible reasons for not treating these two subreddits the same. Either the admins are a) clueless nitwits who don't know what's going on with their own site, or b) sympathetic to one but not the other. Which do you believe is the correct explanation? Can you see any other possibilities?
If you're in my house, I'm going to hold you to a much higher standard than "not blatantly illegal". If you resent Reddit doing the same, well, the Internet isn't lacking for dank underbellies.
Because that's what the admins have basically said, by their actions.
