catholic communities

Am I the only one that notice that in the catholic schools/churches there is a lot homosexuality going on? Don’t get me wrong it definitely is happening in many churches of many religions, but I’m confused because I was taught that homosexuality is a sin so what’s going on here? This is also why I don’t do religion and /or judge people because if we all were created in his image (GOD) at least I believe that’s what the bible said, or maybe I was just taught that too lol then what does that make him? I am not bashing any religion/belief by any means, I’m simply asking for clarity.
