Dear Matt Damon,
PLEASE. SHUT. UP.
I have liked you as an actor ever since School Ties. And I'm sure you're a good guy. But recently, it seems as though every time you open your mouth your Straight White Male Privilege comes flooding out and it is EMBARRASSING.
this most recent slip-up, I most definitely can. "Actors are more effective when they're a mystery," huh? So by that yardstick, you must be a pretty damn ineffective actor, since everyone knows a whole lot about you - we know your best friend is Ben Affleck because you told us when doing the rounds for the film you wrote together (Good Will Hunting, one of my favorite films), we even know who your wife is because you bring her to premieres with you and thank her in award acceptance speeches. And because of that, we know (GASP) what your sexuality is!
So at best, Matt, by saying this you are showing that you are completely ignorant of how your own craft works, and at worst you are saying something extremely damaging to gay people. It's not exactly homophobic per se, but it promotes homophobia by suggesting that gay people should not say anything about their homosexuality at the same time as you and countless others flaunt your heterosexuality around the world without giving it a second thought.
