I'll refer you back to
Terminal Blue's post earlier in this thread. Does that seem like an appropriate response to one person committing a crime?
Their "hosts"? When they are French citizens and many off them have been born in France. This is some extreme level of othering you are doing.
Besides, do you feel like France ought to force everyone who votes for Front National to leave the country too for being racists and homophobes? There's a weird double standard here where good ol' conservative racism, sexism and homophobia gets a free pass while Muslims who are the same should be forced to leave in any way possible. I am absolutely sick of that triad of nastiness being trotted out by people any time the topic is Islam only for those same people to conveniently make excuses for Le Pen, Trump, Wilder, Åkesson or any other right wing politician that exhibits several of them. If it is fine for Le Pen to be openly homophobic (though she has gone to trial for it), then the same should apply to any random Muslims (who should also be trialed if they are inciting homophobia).
Except those women in burkinis got targeted because of a ban applied specifically to target Muslim women who wanted body covering swimsuits. France does not have laws against being topless on beaches. This isn't even a comparison, because your example hasn't happened since the 60's or so.
