Shopping – Your post does not answer Haimy’s objections. He did not compare forums to chat rooms and he did not state an opinion on either.
His point was that Loshon Hora and Onaas Devarim are assur whether online or offline.
And no, one should not try to “develop a thick skin” if that means becoming insensitive to Loshon Hora and Onaas Devarim.
Kol Hakavod Haimy, for “not having a thick skin” and being sensitive to these issues. If you continue participating in this forum, I hope that you are able to maintain your sensitivity and not “develop such a thick skin” that you become insensitive to L”H and O”D.
Shkoyach!
