What's more important, the destruction of the dollar, run away inflation and the collapse of the American empire? Or gay marriage?
I think the issues you mentioned take precedence over an issue like homosexual marriage. But that's really a question based on a false premise: that discussion one issue means the exclusion of the others. That's simply not what happens. There are extremists who try and censor discussion of issues they don't like, or people who disagree with them, but that doesn't make the issue go away.
Plenty of people are able to discuss multiple issues.
