You haven't offered any conceptualization for what you mean by attack beyond people barking at others. And when two people [or more] talk about something they are passionate about and there is a disagreement odds are their voices will be elevated. Regardless, I will assume that you mean criticize, since in 2021 any criticism is considered an attack.
So here is what your argument appears to be: People who criticize others are bad. You also say that humans are desperate for attention and that not everyone wants to be the same...
P1: People who criticize others are bad.
P2: Humans are desperate for attention, but people shouldn't be the same...
But if we shouldn't all be the same and go with the herd, shouldn't we criticize others' opinions even more. . . But, as an aside, there are some opinions that are really truths that are non-negotiable.
