Apparently Milo Y. is getting run out on a rail. I assume you know the details from other sites.
The thing about that guy is, he's got some real guts. That's what lets him stand up, as he did after the Pulse shooting, and talk about radical Islam in a way that would make him personally a target for violent jihad.
A guy like that has merited the right to an opinion, even if it's one I regard as entirely wrong. For a long time, he's been put forward by the Right for the very quality of spouting offensive opinions to Leftists. Guess he found one that makes the Right want a safe space.
I think we could survive a debate on the question, personally. For one thing, there's plenty to draw on in the Greek tradition -- start with the Symposium. It's not necessary to run and hide from the idea.
For another thing, it's an opinion that turns on an issue that the Right really ought to challenge, which is the currently-accepted orthodoxy that sexuality is set permanently by biology.
That aside, I'd let him speak just because he's proven he's got guts. I can hear and entertain an opinion I don't agree with, if the person bringing it forward is someone who's worth taking seriously. Not everyone is. Someone who's manifestly willing to die for what he believes, however, presumptively is until proven otherwise.
