Not being on that particular forum I can't comment on whether you're being insensitive. However, I can certainly empathize about needing a thicker skin to participate in those fora. That, my friend, would be why I'm not on that forum: because I DON'T have that thicker skin. I hope you are able to grow one, let go, or avoid the triggering situations, as seems most appropriate for you.

(hugs) if you want 'em.
