Homosexuals have been murdered due to simply being a homosexual.
Homosexuals have also been discriminated to the point that they have suffered from physical and psychological abuse up to and including being demonized by the ultra-self righteous. There was a time in this country where this was all very mainstream.
There is a reason such "corrupt" organizations such as GLAAD exist.
As for Janssen's profanity, whatever. Insert the current blue-ray of today's most popular "cutting edge" comic, and you'll hear basically the same thing. Is it crude and crass? Absolutely. But Janssen was being real, and I think that was the best part of the interview.
As for his "homophobic" comments, I don't think it was specifically targeting gays. I think it was targeted more to an opponent he thinks he can "get off his game."
I think GLAAD, Janssen, and the Devils handled this well. GLAAD pointed out that this is an opportunity for Janssen to do some philanthropic work on behalf of the LGBT Community, should he choose to do so. Janssen, realizing he put himself in a situation where he could be taken out of context, "manned up" and issued a formal, seemingly sincere, apology. And the Devils posted Janssen's apology without further comment.
The right to free speach doesn't mean you get to escape the criticism, or acclaim, that comes with it.
