You sound a bit like me. Quit being so hard on yourself. I ruffle feathers on other forums sometimes too because I don't like to pull punches much but, if you aren't really acting mean or callus about it, I wouldn't worry about it. Also you ARE going to sometimes run across people who are easily offended. That's normal though whether you're online or off. You can't please everyone and you shouldn't feel like you have to. Took me a long time to figure that out. I think it'll be alright.
