If you agree that humans alone can't claim what is universally right and wrong, then that is a first step towards religion, but I will leave that aside.
It seems like you agree that you have no basis on which to claim, with a degree of authority, that someone has to adjust their actions in your vicinity. If you don't contest this then I will leave this discussion, as you have confirmed, that you can't just forbid others from dressing in a certain way.
If you do not agree then I would like to understand how you can say that "morality is an entirely human inventes concept, no one has any foundation for it..." and then go on to say that somehow you can in fact impose your morality on others, as I understood it because their "made up stories are just way stupider than others"? According to which scale? One that does suddenly pop out of nowhere and is absolute for all humans?
