I have no reason to believe I'll actually change your mind, but here goes.
Yes, gays have it much, much worse in parts of the Middle East. But you wouldn't complain about people in the US advocating against gun violence just because there are more murders on another continent. It isn't great here, and over time it can be a heavy weight that never lets up.
Imagine being a tween and suddenly crushing on the same sex. People on TV don't do that and you know your friends don't. You've heard your parents talk about their asshole faggot boss and how his unnatural life choices male him a terrible person. Your pastor talks about the horrible gay agenda during youth group. You feel like you're some sort of monster or alien and try to change the way you are so that you aren't like those awful people who everyone hates. Maybe you go deep into denial. While your friends date, you also have a chain of failed relationships with women trying to somehow fix what's wrong. You blame yourself for those failures and sink deeper into depression. Eventually you realize you can't change it, but you've already seen the one out gay kid at school get bashed and have his locker regularly vandalized. You know your parents hate fags and would probably throw you out if they knew. Imagine hearing your friends one day at the lunch table talk about what they would do "if a fag ever looked at [them] the wrong way in a locker room." The consensus at my lunch table was to beat them unconscious. You can't tell them either and need to make sure no one at school ever notices. You eventually find a guy who shares your feelings and you connect. It is a revelation, but you know it can't last. He suddenly ghosts you after a close call with his homophobic parents. You spend the rest of high school trying to stay below the radar, at times choosing to be bullied for being nerdy because it is a good cover.
That's what roughly happened to me. It's happy and positive compared to the stories of some of my friends who were tossed out and homeless by 15, or others who were sent to conversion camps and beaten for 6 months. Afyer college I came out to my parents and have formed an unsteady truce, but I still have to be careful when I visit because people get bashed in my hometown even now. I have to balance who knows at work because I can be fired for being gay. A friend of mine here in town was forced out of their apartment by neighbors who called their landlord about the fags next door.
Though we have made great strides, it isn't perfect in the US. For teens even now the atmosphere can be very oppressive. It's very hard to convey what it feels like to deny or hide such a core part of yourself and live in fear of it. It should be no surprise that suicides result.
