A person that has already eschewed the moral code of society to such an extent would not be phased by their targets' words of disapproval.
A voyeur would consider the risk of being yelled at, reported to a local authority (such as a bar owner), being thrown out of an establishment, etc. They would consider these risks and weigh the consequences and determine that they are worth it in the end. They would still get what they wanted, and would be free to carry on their activities in the future, perhaps at another establishment or after enough time had passed.
But the risk of physical violence, that's not so easily dismissed.
