While I can't say I know you I would say just be more careful in the future, if someone is offended by something you say then ask yourself how serious you should devote to defending yourself.
a famous quote I will put here is "you can please some of the people some of the time, but you can't please all of the people all of the time."
example: I don't like dogs, I just don't. Some people think they are the greatest pet to have in the world. I think a cat is better. This fact pissed someone off once on another forum and they tried to convince me otherwise. They obviously failed and now I don't speak with them. Most people wouldn't bother getting as upset over it as they did. I honestly don't know what exactly I said that set them off. but point is people get upset over some of the most random stuff. Just be yourself and be careful of what you say if you don't want to offend someone.
