It goes both ways, brother. For instance, in an effort to get your point across you found it quite easy to generalize a whole swath of people based on the interaction of a few people that you may know personally.
Though this doesn’t relate at all to the topic at hand, but some ignorant folks on the other end of the spectrum might raise the argument that they’ve never met a person named Umar or Abu Bakr from the Shia brethren. I know, that probably isn’t valid, but you get the point I’m raising?!
Islam came to extinguish Jahaliyya, but it seems that some who claim to follow it have yet to give up some of the Jahalat because they identify with one or another clique. May Allah guide us, and unite our hearts on what is common, and give us all the taufeek to leave minute matters which only cause a divide.
