On the subject of the burqa - Mr Farage says that they "oppress" women. However, by introducing a law banning them, he's replacing one firm I'd oppression with another.
If you posit the idea that Muslim men are forcing their women to wear burqas, then a non-Muslim man banning them is doing the exact same thing, just in the opposite direction.
Not sure where the UKIP is particularly interested in women's rights. I'd be curious to here their stance on other equality measure (equal pay, child care provision fir working mothers etc).
I suspect that if we went looking for those policies, the cupboard would be rather bare.
