Plenty of cultures don’t have the shame around nudity that we do. It is not at all universal and feeling humiliated is just that, a feeling. You can choose to feel a different way if you want.
You're mixing two things. The fact that there are nude beaches in Canada for example doesn't mean the women want sexualized nude images or wouldn't feel embarrassed or humiliated by that.
There an important contextual difference you are missing.
This whole you can choose is rubbish. It can be used to excuse any form of victimization. It's not sufficient to hurt, violate or victimize someone and tell them to choose to have a better perception or attitude about it.
How about the people doing it change their attitudes on others privacy right and right to their integrity
Further, any efforts to impose real consequences on the victim such as denying a job or expressing that they should feel shame (as if they have done something wrong) are also unhelpful and should be roundly mocked and derided.
