"Oh, so because I’m straight I’m not allowed to have an opinion on [insert LGBT issue here]"
I’m an english major. I know next to nothing about science, engineering, and astronomy. Sure, I think space is cool. I’m very supportive of NASA’s efforts. I might even have an opinion on where we should send the next shuttle or how much money we should spend on space travel.
But at the end of the day, my opinion on the matter is not valuable. I’m not going to enter into a discussion about the next shuttle launch with a bunch of trained scientists and expect them to take me seriously.
Sometimes, your opinion is not valuable. Sometimes, you aren’t qualified to enter a discussion.
And, lets be honest, straight people’s opinions are valued in literally every other situation. Hell, straight people get more awards for lgbt “activism” than queer people themselves.
If you really can’t accept that sometimes your voice isn’t the most important in the room, you might need to get over yourself.
