Part of the problem is us. We throw out Freedom of Speech as if it's a catch all to say anything. It ain't. More importantly, this: Freedom of Speech, is not the same as this: freedom of speech and they shouldn't be used interchangeably. Unfortunately, that's what we do all the time. FoS is a constitutional right of expression without
government restriction.
MR decisions don't fall under gov't purview. In fact, there is no presumption of freedom of speech in any private forum. We're all bound by MR's rules and regs. To assume we have freedom to speak as we please is in this forum is incorrect and entirely our fault for making that assumption. That not only applies to MR, but any forum.
I can't pop in a thread and start dropping f bombs all over the place or disparage someone's mothers all in the name of freedom of speech. Well, I can at Deadspin, but not here.
To answer your question about censoring social issues. I don't think they need to be censored. I don't think we even need a PRSI. Completely irrelevant though. It's not my site. I do understand why it exists. Everyone isn't reasonable.
