I wouldn't let him remain on the forum at all.
being a genuine american; I am one to let someone voice their own opinion or act their own way.... but am not ok with them having a position of power with such little regard I have seen him have.
when I added DT to my trust; I started going through each members posts; about 10 pages each.
several persons posts; made me rethink that shortly thereafter... and his responses towards what I had to say; were very inappropriate to say the least. I now just have the people I have had dealings with, or that I have come to trust in their conduct and conversations.
If it were up to me; he would not be in a position of trust given just on his method of interacting, discussing and solving disputes let alone other things; but I would only ban him as a person if the greater amount of his posts after a direct warning from me; were to continue to be off-topic or completely superfluous as many of his have been recently.
To sum:
I think even the stupidest of people in the world deserve a voice. I'm not calling anyone specific stupid, it's all encompassing.
This statement however, does not mean that I will empower them or support their outlandish or illogical statements.
