I won't posit that I was completely innocent in the matter. People around here know me by now, I have tendency to get a little carried away when it comes to subjects I'm passionate about and often I'm more aggressive about it than I should be, but in my opinion (and maybe I'm wrong on this, seeing as I have a very strong bias in this case), but if you openly mock someone for being sexually abused, you're definitely over-stepping a boundary.
I'm not at all surprised that the individual said the things he did, as it's not the first time I've seen his posts on this forum, but what I am surprised at is that MyGaming's actions regarding this seems to have ended at locking the thread. As I said, I'm obviously biased in this, but in my opinion if you mock someone for being molested as a child, then it's clear you're not emotionally or intellectually mature enough to be a member of a civilized forum. In that case, you should be banned and supplied a link to 4chan, where you'll fit in.
