Try to be careful when you write, but in the end I'd say just go with it - if you involuntarily offend someone, you can always say you're sorry later, and clarify. You may offend a couple of people sometime (it's probably inevitable) but I don't think that has to stop you from writing here. Just try to be respectful and things will be ok. You can read other people's posts to learn better. I think you're doing great
