Meh, I think it must take guts to choose to wear the veil in the UK.
I suspect the reality is that some women choose to wear it, some women are forced to wear it, and some are in between, where they feel under social pressure to wear it, but could choose not to. I think it's as nonsense to say that no one chooses it, as to say that no one is forced to wear it.
I have a big problem with the idea of a ban. Not sure it would practically help those who are forced to wear it, and I'm very uncomfortable with the government telling women how to dress. We need to find a way of supportive suppressed women, but this isn't by banning items of clothing, but through increased opportunities for women, and more opportunities for social integration (which would be hindered by banning the veil).
For me, my breasts and genitals are not for public viewing. That's ok, as we tend to wear clothes covering them. For some women (veil wearing Muslim's), their face also falls in that private category. To say they need to uncover their face is as intrusive surely as asking me to walk round naked.
As for five year old wearing the niqab, I've never heard of this. Even back in tacloban Afghanistan, I thought young girls were only expected to wear a scarf, if that. I thought it be a me more restrictive at puberty. This does make make me doubt thst posters story tbh.
