I think your perception of this issue depends so much on if you know gay people that are an important part of your life. I have a son that came out this Spring. Great kid (I say kid....he is a junior at university.....but your children are always your kids). Very bright. Played sports in High School. Played in the school band. Has great friends (very accepting of who he is). Really, has so much going for him. Frankly, I think I knew this about him since he was 5 years old. But, I figured he would tell the family when he was ready.
Here is the thing, and the reason for the background info. When he told us, he said: I suspect you guys kind of knew, but there is really no easy or good time to do this (come-out). So, here is a kid with lots of stuff going for him and parents that are accepting.....and it was still a tough thing to do. Straight people don't face this issue.
Of course, we told him we love him and that doesn't changes because he came out. I also said: never try to hide or apologize for who you are. That just puts power in the hands of the narrow minded.
Now, I have another younger son. Another great kid. But, he is different than his older brother....different interests and strengths. I suspect I will never have to say these same words to him. I know there are certain things that will be easier for the younger boy.....and he won't face possible prejudice just because of the person he loves.
So for those that think gay and straight people don't face different issues, I would respectfully disagree. For example, Apple does not make a "straight" watch band because it is just a false equivalency when compared to the discrimination and prejudice that gay people face.
