I want a burkini. I'm not a Muslim, I grew up in the UK and I am assimilated. But last summer I was caught out on a trip to the seaside (in France, ironically!) and made do with Capri-leggings and a rash vest. I felt so comfortable swimming in them. Much more so than in a regular tankini.
Why should I not swim covered up if that is what makes me comfortable? What business is it of anyone else?
This isn't about separating religion and state. This is knee-jerk xenophobia.
The fact that other women in other countries have it worse does not diminish this situation.
