You are delusional. This hygiene law is very old. I think it is a weird law but it has nothing to do with Apartheid or discrimination against Muslims. It is just a weird law. If a non muslim woman visits a Muslim country she also needs to dress accordingly. Which is just their law or is that white christian/atheist Apartheid to you?
Colonization and what happened in colonies is a tragedy. That should never have happened. But I don’t think they came up with their pool hygiene law to discriminate against Muslims.
And for the Seine… Atleast they tried and put more than 1 billion euro into getting it cleaned for the Olympics. Before that, there was a ban to swim there.
