As for schools of thought. These are Fiqhi schools, ever rotten Marja' is a fiqhi school (they differ on tons of issues, from najasat, to the ruling of the jumu3a prayer), so don't be bothered by the cheap shots of the Rawafid. What is important is that you are a Muslim now (whatever fiqh you follow) and not an Imamite Mushrik.
