It already is illegal to expose oneself regardless of the gender.
This issue is like the ridiculous category of a hate crime murder. Murder is murder regardless and designating it a "hate" crime is meaningless.
“It already is illegal to expose oneself regardless of the gender.”
Not anymore. Not in a women’s restroom or shower etc...
And if someone complains about a naked man in a women’s/girl’s shower, say at a public pool, the complainer is the criminal.
