With the exception of the bold part, the rest are just half baked facts. Who says you don't have freedom in Pakistan? and who the hell told you that girls can't go anywhere without a male escort?
When was the last time you visited Pakistan? I bet 20 yrs ago !
Some girls may go out by themselves or with freinds, but i've noticed that alot of us who are born/raised here (in the west) still have very strict family back home who observe traditional rules, one of which being girls cannot go out unescorted.
I would live in UK just because of the freedom. simple as that.
