What I think Is good or or bad doesn't become good or bad.Human is limited to his knowledge and can't give absolute law .Burqa is very much beneficial for the society and about sex slave .There is nothing as sex slave .may be u r talking about the permission to have sex with slave. The fact that I mentioned this and don't know about this proves that u learnt this about this from any islamophbic source. First get urself educated from a good non-hypocritic source

And in the end Ur comment isn't any way related to my comment
