after reading some comments , i see some of you dont know much about islam , they think its a killing religion , but anyways i believe people who hate islam are just so confused , im not telling you to be a muslim or anything but hey! give it a chance and read my friend .... (dont get angry)
Islam = 1 god (have no son , no wife , no mother .... think about it)
Islam = Dont kill Noone! (its in quran, not internet or media...) but Only if they wanted to kill you (and thats your right) .
Islam = Peace , Love , ..... read and you will see your it self. (Dont read on websites that hate islam .... )
I love islam and i love your religion ....
I am confused

Why do some Muslim women wear burqas or head gear, are they required to do so?
Depends on who you ask. Christians are absolutely forbidden from eating shellfish. But most Christians don't even know that.
Christian women are REQUIRED to cover their heads also. But again, since most Christians don't know this and we have little cultural connection with the writers of the bible it is ignored. (Spoiler Alert Most Christians are going straight to hell, lol)
Most Muslims would say that you must dress modestly. What does that mean? Depends on who you ask again. A conservative Muslim might say that you should cover up your body as much as practical. This is not a rule for women, men should also be covered. They should wear long pants, long shirts, and wrap their heads. Another Muslim might say you don't have to cover up except at the mosque, but you should not wear skimpy clothing in public.
1 Corinthians 11:6 King James version
"For if the woman be not covered, let her also be shorn: but if it be a shame for a woman to be shorn or shaven, let her be covered."
