Second, I dont know if you notice but people copy any type of behaviour that is seen more, the type of thing becomes normalized, and as an example was the deepthroat that women can’t possibly enjoy, but do it anyway because it somehow becomes expected of them to do so, some even start enjoying the act even though it is not pleasant, it’s a coping mechanism...
Violence on TV is obviously affecting our society for sure, and violence suffered from the same capitalistic fault to maximize profit, violence initially sold well so it produced exponentially more until the last dime could be extracted out of it.
If no financial incentive is behind any of these “memes” then maybe the better ones become normalized and the effects on society are less nocive. Speaking broadly ofc.
