It's funny how something as in-personal as a comment on the internet can sometimes have such a strong effect on us personally. I think we've all been through it.
But don't take anything at a personal level. Opinions are just that... opinions. It was great that you decided to apologize, even though you still aren't sure whether the comments made to you after your little splurge were really necessary or justifyable. It shows maturity.
We're all glad you decided to stick around.
I would also like to point out that many times we, "the reader", infer emotion or connotations that were not necessarily intended by the person posting. When in doubt report the thread or pm one of the mods so we can make sure that no one is being attacked personally or getting too off topic.
Glad you decided to stay and I look foreword to seeing more posts.
