Cosplay is just a hobby.
Obviously, old people think it is immoral to wear strange clothes. She can't understand and accept these fashionable things. Man is a stupid animal, and instinctively attacks or escapes from the unknown.
What the old lady said to the girl caused slander, personal attacks (saying that the girl is a wave and has nothing to do), much ado about nothing (thinking that the granddaughter's study is not good because the girl goes to Cosplay), bullying the weak and fearing the hard (the girl has been silent, of course, it may be that the girl is unwilling to waste time and breath on her).
Empathy, the old woman obviously didn't do it. If she dances square dance, have you ever thought about bringing trouble and trouble to others? Can you also say that my grandmother doesn't even eat rice or do housework because of your square dance?
No wonder her granddaughter has poor grades.
If a boy or boys (or parents) follow, does she dare to bully two little girls so arrogantly? This kind of thing in society is mostly that these people bully their mother and daughter (such as giving up their seats), or two or three ordinary girls. But few of them are aimed at men and women of the same age or multiple men. Think about it, if this
The old woman faced several strong men. Cosplay is dressed strangely. Does she dare to fight? It is human nature to bully the weak and fear the hard. The terrible thing is that you don't know that you are doing evil.
This society pays too much attention to morality, but a normal society is based on a sound legal system. The girl's dress, words and deeds did not violate the law, nor did they bring trouble and trouble to others. Everyone has the right to do or not do things that are not prohibited by law. For example, whether the subway bus gives up its seat is also true.
Therefore, even if you don't give up your seat, there is no illegality, and morality can never be above the law.
