"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…
So yeah I suppose you have a point, but your anecdote about not knowing anything about Science, Engineering, and Astronomy doesn’t apply to "Oh, so because I’m straight I’m not allowed to have an opinion on [insert LGBT issue here]" because we don’t have enough information to know if they are knowledgeable in LGBT issues or not. So it makes it out to seem like you’re saying that because said person is straight they automatically don’t have the right to speak about the issue and be heard. Which is just as bad as saying that just because a person is not straight they don’t have the right to speak about any straight issues (and even if they don’t really exist is not the point). Equality does not mean pushing away others rights to make room for your own, it means working to obtain the same rights as everyone else.
