To me, the burqua is a garment of exploitation, intimidation, oppression and, indeed, torture, for the wearer. I cannot imagine a case in a free society where anyone would choose to wear a burqua without being brainwashed.
Therefore burquas and face coverings should never be forced on those under the age of majority.
I think it would be safe to assume that, if a young woman were to take up the wearing of an all encompassing, stifling, restrictive garment at the age of eighteen, there would be an element of rubbing others' noses in it.
If the wearing of face covering was a religious duty or a neutral act then men of the culture which advocates them would assume burqas too. But they don't as we all know they are a low status garment originally designed to protect women but which are now used to keep them in their place. A burqua on a man would be a garment of shame and humiliation.
There are a variety of reasons why Islamic and other women cover their faces from a fear of their menfolk to a now radical desire to provoke those perceived as 'other'.
We ought, in a free democracy, to protect women from being oppressed - and remember the burqua goes hand in hand with other horrors such as FGM, cousin marriage and forced marriage. And if faces are covered to provoke and offend then this is not acceptable either and should be stopped by a general ban. We do not tolerate nudity on the street or the bearing of arms for good reasons and we should not tolerate burquas.
To be honest, I don't care if Bojo or Jeremy Corbyn or Ronald Macdonald criticise the burqua as they would be right.
