Why do you call it "devil's advocate"? I agree! I agreed to your previous comment too. "Coming out" seems to has been very useful for gays' rights. Maybe the question is in which point a controversy is. Is the controversial option legal? Or even are there laws that protect it?

Current revolutions or cannabis are counter-examples.

I'd also suggest to think about the asymmetry of responses. You might express your opinions in public, but someone could choose to anonymously not to hire you because of them.
