It seems like a lot of work - that won't change anybody's minds. The ignorant will cling doggedly to their ignorance. Better to keave their ignorance alone and ignore them. Or alternatively - show them the error of their ways, with a good reply meme (see below). I don't support violent bigots of any stripe - Wahabi salafists included. Sufis are indeed practitioners of a religion of peace. The way to reach those idiots is to open their eyes abd hearts to the truth. Erasing their posts would also remove the public evidence of who they are. Create tags that reflect your own position.
