I wouldn’t say that but the thing is that shia parents should not teach their kids to swear and say bad things about beloved personalities of muslims.
I remember when i was a school kid we had this shia kid and he said that when he grow up he would kill " Hazrat Omer razi Aa Taalaa " Noazbillah. I told my dad about it…and my dad told me that shias teach their kids such things.
So, i guess its their parents who teach them such stuff. Anyways as I said both parties are responsible for this tragedy. Inorder to avoid such things in the future a careful examination of deeds is required.
