You may be racist or nazi lunatic but still be a trustworthy person. Racism has nothing to do with trust.
I agree.
P.S. Death threats are not matter of trust as well. These are matters of either forum rules or the court system.
I disagree. Trading with such person carries a direct risk if that person learns your address or other information that would allow them to act on those threats.
Granted forum rules
should take care of that and normally they do, but unfortunately in this case the person was banned only for 180 days, not permanently.
