The two aren't mutually exclusive.
Here's what they are actually saying (I think)
On the one hand: hahahahaha good luck getting people to stop rubbing one out. I'm pretty sure God doesn't care if we use the gift of orgasms as long as it isn't harming anyone. You guys can chill over there and not touch yourselves, but don't tell me what to do with my own ladyparts.
On the other...is this thing making fun of sign language/interpreters/deaf people? What exactly are we laughing at?
Let's discuss, shall we?
