In the west no woman or man can be forced to do anything by their family members.
Here in the UK anyone who is forced to do anything by anyone can contact the authorities. e.g. many ignorant Paki parents try and force their children into arranged marriages (not because of religion but because of their backward village culture) but a lot of those children go to the authorities and they are given security and shelter till they can fend for themselves because this is a welfare state..
Whether burka is or is not a part of Islam is irrelevant. It’s the Europeans hypocrisy which is the issue, on one hand they claim to have monopoly over freedom of expression so that they can insult our Prophet 
and then they deny that right to others who simply want to practice their religion and don’t want to hurt anyone with a piece of silk or a tower.
Hollow European values are a joke. What a farce…
