This comment makes zero sense in this context.

The parent poster said he was for defending free speech, why would he want to switch places to somewhere where it's restricted?

What is your objection even? That because free speech is restricted in e.g. North Korea we should start restricting it elsewhere?

Or are you implying that oppressed demographics(e.g. homosexuals, black people, etc.) are having their freedom of speech stifled and therefore restrictions in free speech as a result of the 'safe space' movement are justified?

That's the only reasonably understandable(albeit flawed in my personal opinion) interpretation of your comment I can really make.

Care to clarify?
