I also think that now after the taliban the burqa symbolizes them. The burqa is now either a thing that you are not allowed to wear somewhere or forced to wear somewhere it does not sound good i think that it makes it sound worss if its banned somewhere but forced somewhere else
I agree with you theyshould be able to wear it to church because it is religious but they dont have to wear the burqa all the time if they would like to wear it the perfect time is church because they are already close to allah there and then it will make them feel closer and it could be a special thing that they do
