alosso:And, is it derogatory to name a person a liar who is making voluntary false statements which he cannot prove?
I've agreed with you (in parts) before and I haven't butted in this thing for a while, but.... can you prove these statements are false? Cause otherwise, technically speaking (and you've been doing the same for a while), you're calling people liars with no proof and what does that make you, in your own terminology? ;-)
P.S.: In total agreement with Carlo, that the reasons for banning people should be made public.
Edit: Just thought of this, but following your logic, do you frequent religious forums by chance? Would you call everybody there liars as well. Cause basically every religious person is talking "facts" about things with MUCH less proof than here. And they believe those "facts". I personally don't, but should they be called liars for believing in something, they have even less chance of proving than what we're talking about here? I hope not...
