sir i hope you are not making the same mistake regarding salafis that i made some weeks ago: of putting all of them in one basket based on our 'experiences' with some of them. i still don't think it is a good idea to become salafi (esp the extreme ones). yet having looked into the matter in some depth one can say there are many flavors of salafis. what you mention seem to be some extremist group which are going to be renounced by other 'salafis' as well. yet many would take him to be the representative of all salafis (many actually do think all of them are like that) and hate all of them.
