Picture shows a pride parade. A group of people are carrying a banner that says "LOCKHEED MARTIN" over a rainbow graphic.
I know it's difficult but you don't speak for everyone that isn't straight, you don't get to decide what the whole group thinks.
Having sex with people of the same gender is not a political position, sexuality does not determine political and moral views. Plenty of gay people have political and moral perspectives which differ from your own and they are still valid in their sexuality.
Pride should be for everyone who wants to celebrate LGBT, it's not a political party. Yes that means people you don't agree with politically get to celebrate too.
