As per my minor knowledge attatching one's self with any particular sect is not at all binding upon us..Sectarianism is one biggest threats of many others which has brought pakistan on the verge of destruction today.In reality we ourselves are not following our religious values in its true spirit, this is the mere showboating that exists now.Its all about KALMA TAY'YEBA, extract its real essence and one will surely derive the fundamentals of Islam on which we have to get on!
