At what age should I force my daughter to wear the hijab/burqa?

Never.

Imam Obama, the libRETARDS messiah, will be informing you about this soon.

How about never.  Me thinks you are a troll.  If you were actually a Muslim you would already know the answer to this question.  Muslims I have known do not make their young daughters cover themselves.

Never, you stone-age desert troglodyte.

If you live in America, dress like Americans.  If you want to dress your daughters like you still live in the country you left to come to America, then why did you come to America?

Leave your old ways in your old country -- or go the f*ck back to it.

culture not religion determines dress

why did you move to the west?

"FORCE" is the big reason why there is so much argument between cultures

If she was born into a jungle tribe she could be "modest" with no clothes as all.

Just as a question; why do some cultures get so upset about the sight of a woman's body?

I do understand sort of, it was the same only a few hundred years ago in some of the western countries.

I DO UNDERSTAND that a parent does not want a young girl to be too sexual before she is old enough to have good judgement.

pay attention to your wife, she is a mother and a woman and probably knows best

Sallam Alekum, Shalom, Peace Brother, Relax

Most muslims wear western style clothes.
You should see how well the GAP does in Indonesia.

Maybe you should move out of Saudi Arabia.

if you were sincere you would know

I'LL TELL YOU WHEN

You should make her wear the hijab/burqa for her modesty when
you yourself start wearing a hijab/burqa for your modesty.

By the way, your daughter shall grow up hating you.
Don't say that nobody warned you.

How dare you prevent a person from enjoying the beauty of the sun
hitting their skin or the wind breezing along their body just as god
intended it to be, because god created the sun and the wind.  

So you will take these things away from your daughter?  Shame on you.
Why don't you just lock here into a cage while you are at it?

I am a man and it appalls me that any man could act so non-caringly
toward his precious daughter.  Shame on you.
