As always with these issues, people get confused between disapproval and things being made illegal.
"People have the right to wear what they like". We never said they don't.
Saying that we disapprove of/feel disgust for men wearing stereotypical women's clothing as a sexual fetish, is not saying we think those men should be arrested or that the practice should be legally banned. It's simply saying that we, personally, disapprove and are disgusted. And explaining why.
It's not us that use and abuse the police and the law to coerce people to accepting their behaviour.
There are so many behaviours that I disapprove of that I don't think should be legally banned. I disapprove of fathers not spending time with their children, I disapprove of extra marital affairs, I disapprove of sulking. I don't think the Law should get involved with any of that.
Similarly I think men wearing "sexy" women's clothing is totally gross. But I'm not calling for it to be banned. I'm just calling it out as gross and I think that the vast majority of people probably privately agree.
