I’d argue that they are not being disagreed with because of what is “socially acceptable”, but because their comment added no additional facts or information, and was instead just a couple of opinions without much to inform them.

This user was downvoted for his views which are the rough equivalent of "she was asking for it".

To see this as people simply being closed-minded to different cultures is really myopic.

I personally refuse to hold people to different moral standards because they come from another country.
