Double standards

So I came across a post where a girl was rejected because of her short height. Firstly its completely wrong to label someone as red flag only when he just rejected a girl for being of short height because everyone has preferences, it's his choice period. If she is short then she is short. But if someone made fun of that girl and rejected her making fun of her short height then it is a 'red flag' and it is body shaming. No one has right to categorize people to good and not good basedona their physical features. Some people in the comments were attacking on that boy for rejecting her which is completely wrong and some were attacking on girl saying height matters and girls aslo do this blah blah blah. Why people just can't be rational and give logical answers. It was just about preferences and nothing else and not that you should attacksomeoneo for having preferences or attack someone for their body just because you were rejected by the opposite gender for same...All people in the comments were just insecure for something or gender biased. Those same will say something completely different on the same thing after few days. Edit(not much related to this post) : everyone has different opinion , there was literally a person in that comment section saying come to us for studies and we like short girls, like come on man, stop😂. That comments section have 100s of different opinions that are far different from each other.
