I don't think "offended" is the word I would use. The PoX and the Priesthood Ban absolutely played a role, but I felt more confused than anything.
I always felt welcomed by the community and shrugged off any interpersonal issues. So no, I wasn't offended in that sense.
But I was offended by some of the doctrine, or at least certain people's interpretation of it. There was one fifth Sunday (BYU YSA ward) where we were told in advance to prepare questions about relationships - any kind of relationships, family, friends, romantic, whatever. Then when the lesson came, the bishopric spoke for the entire time on why our salvation depended on getting married, why now was the best time to do it, and gave some really bad and sexist (to both men and women) advice on how to do find someone to do it with. Besides being asexual, I was also 21. My roommate was 18. My best friend a pew over was openly gay. It was almost comically out of touch, but everything was from the words of the prophets so we didn't dare laugh. Offended might be a good way to describe how I felt that day. When I got home I thought to myself, "Is this really what the church teaches?". I didn't leave over that lesson or others like it, but they certainly contributed.
