How much leeway do you give a new poster who is clearly a new Avatar of a recently banned member?

Specifically there was a member EB1945 banned from the Agoracom GNH board who then began a neg campaign against Agora and GNH on the SH board.

He is now back at Agoracom GNH, under a new Avatar (Liberal), making sly comments about the general discussion and referring to the general population as "idiot's" , "blowing wind" and using a condescending tone to the overall posts.

He refer's to himself as intellectually superior and that the board members are somehow inferior by virtue of their views. He doesn't really cross the line but skirts the edges by not targeting any specific poster rather the overall board.

The Avatar reference is clearly meant to convey a political view, and as such, we do not want to be seen as censuring. The poster has made negative reference to persons of right of center views. (not that it matters)
