It's neither necessary nor unnecessary, it's just me posting in a thread. If they're hurt, that is not my problem, I can post what I want. Also, if they're hurt, maybe they should be because obviously, if they're hurt, they believe what I am saying.
Yes, it's you posting in a thread. The problem is that it was you posting in a thread as a complaint about somebody who is already troubled. It's not the place for that. Take it to a pm if you want. The point is that complaining in a public place about a member just because of something they said (or lack thereof) is bound to cause a stir-up.
EDIT: My apologies, Curm. You ninja'd me.
