Comment by Smushman

It is just a fact of our protective psychological human makeup that we all have fragile egos and energy conservation always on. That will make us insensitive and upset with others (we respond rudely), and keeps us safe by not wasting energy on unimportant things (we don't submit).

Both you as the submitter who doesn't want to deal with the comments, and the person who is complaining back (and to be sensitive myself, I try to remember they may not be conscious of it) are both dealing with that.

For example, think about your job, and how often did you just let things go because you had to 'pick your battles' or even 'just too tired to deal with that'. Bosses do it too. This is human nature.

It is, as you say, a people problem.
