to me, subjective: a thing/a thought based on or influenced by personal feelings, tastes, or opinions.
The parent was saying "personal responsibility to fight wrongs": to me, it means some people are wrong (as in they believe something that is wrong, even, if of course, they think they are right). But it is just wrong, not subjectively wrong.
And it is my duty to do something about it (either convince, educate, or even censor,...).
So I guess you are right, I don't understand your point about "But right and wrong are very subjective things and this fighting the wrongs is contributing a lot to the global mess." Because the way I read you is "stop trying to 'fight' the wrong, and the mess will be less".
