Discovered that one in my family is gay

After yesterday's trauma, I decided to suspect that my uncle is gay. I had a feeling because when I was little I saw gay porn on my uncle's tablet but I didn't think much of it. My uncle has been going to this guy's house to supposedly clean the house for like the entire week. I also went through his Facebook. And what do you know. There are private pictures of him naked in front of shower curtains from another house. Also almost all his friends are gay and he keeps reposting pictures and even movies of gay stuff. Also he always watches gay things in public too and my family doesn't even know. To be honest, this is a shock to me. I can't tell my family otherwise they would kick him out of the house because the family is against gays. Personally not against gays. It still shocks me.
