To all the LBGT+ people here

I'm not trolling. I am generally curious because there are alot of insane homophobic people out here. When you see someone you are attracted to; Do you approach them and hope that they are gay as well? Are you cautious about who you approach? Or do you use dating apps? Or meet people at clubs and stuff? How do you personally go about dating? If you are interested in dating. If this is offensive I'm sorry. I just want to get someone else's point of view on life.
