Tznius: I think you misunderstood RY’s comment. He was simply pointing out to you that there is a problem with the way you seem to view tznius. Based on what you wrote, it sounds like you think that girls are supposed to make themselves look ugly and it is untznius to look good. This is an incorrect understanding of tznius and it is unhealthy for a girl to think that way. RY was understandably concerned about you and was very kindly trying to help you by pointing out that you shouldn’t be thinking that way.
Also, there have been men commenting the whole time and you didn’t say anything to them, so there was no reason for RY to think that he was not allowed to comment. (I understand that you thought his comment was offensive, but as I wrote, that was based on a misunderstanding).
You make a lot of assumptions of other posters thoughts and motives. It might be best to allow them to speak on their own behalves.
