Overdone and ludicrous -- meaning both the burkini itself, and the ban on them.
That said, western women once wore full-bodied bathing attire at the beach until very recently, at least the 1950s or so. Can a compromise be found so that Muslim women can wear those older style bathing suits and not bring negative attention on themselves from the police?
It sounds like you're arguing that dressing conservatively is okay as long as the conservative clothing was designed by white people.
Not at all, but that women who don't really desire being ogled at on the beach have the option of adapting/updating the old fashioned styles to something that both the secular and the religious French can still relate to. Cultural adoption and diffusion and all that.
