Oh yes. When I go to toilet for doing my big business, that is sacred too !!!

Well OK, you took Islam (religion) aside. That´s good !!! Because the whole thing actually hasn´t only a bit to do with religion.
You want to talk about Taliban and Al quaeda now ? OK !
But what has it to do with the topic anymore ? What has it to do with an islamic mosque then ?
You´ll have to agree: nothing !!!
But OK. I´ll try to answer your questions honest:
1.)
Talaiban and Al Queiada (SIC) are the true enemies, but do you know why?
Not really but I guess, because you (we) can´t beat them and this is unbearable ?
But there is a mistake in thinking on your side already: Taliban and Al quaida are not the same. The Taliban are only the best or most willing recruits of al aqueda. You don´t make a difference ? You may want to find out first, what´s ´Al Quaeda´, what is ´Taliban´, what are ´Warlords´, what moves all of them and what their different views on power and religion are, before you lump them all together.
2.)
Do know you why Bin Laden wants the US buried and a thing of the past ?
Actually I´m not sure that this is his wish or if he rather only wants to fight back. His internet-messages don´t say so. They want us to leave Afghanistan (Iraq b4). In the case we don´t, they threaten us with consequences (in form of terroristic acts).
Actually I think that´s OK, because it´s their country, their religion and they´re trying to defend what is theirs. Just like our governments pretend to do with our countries and our freedom. Defending it.
3.)
Do you know why the WTC was the Target, Twice?
Of course. Because the WTC was a symbol of american superiority and he wanted to hit you, where it hurts most. He was successful.... (given, that the scenario you believe in, is true)
This is what the united forces trying to do in the same way. Hitting, where it hurts most. And they destroyed alot of their symbols....you have no idea.
And ?
P.S. JFYI: Since ´Yahoo´ seems to be your favourite news-source, you may want to try this:
You should also read the comments on Youtube, posted below the vid.
And btw. : you shouldn´t be surprised, if they start to attack christian churches soon.....

Nothing is sacred....for whom ?
