talking about kids and dead relatives

throughout the show, the baddies have reached a consensus of "don't mention children and dead relatives in an argument" but has anybody really followed that rule? rollie said "fuck your dead dad" to slim and ahna had supposedly mentioned nunu's mom (who's dead), kid, and baby dad. kold killa said "fuck your son" to tavii and dolly said something alluding to sa (??) of kold killa's daughter

are kids and dead relatives really off-limits? so many people have mentioned children, but they were left unchecked. when we decide that talking about children and dead relatives was off limits?
