Hi everyone,
I am a regular MNer and NC'd for this :). As background, I have a successful career in tech, I am a Muslim and I wear niqab too. Since Boris's comments, I've seen quite a bit written on MN about burqa and niqab, and thought it may be useful to answer any questions people have in relation to niqab. I also know a large number of Muslim women and have lived in various Muslim communities, so can probably speak from my experience and relay other people's experiences too.
Just as a note: I don't know any women in the UK that wear burqa and I have never seen anyone wear a burqa in real life. The difference between niqab and burqa is illustrated here: cdn.images.express.co.uk/img/dynamic/1/590x/scarf-651554.jpg
