tamerlan tsarnaev was definitely brainwashed, page-36

Hajji,

"Islam > Instilled right from wrong > Daily life values

Most everyone else:

Instilled right from wrong > Daily life values > Religion"

True Hajji but with the addition of:

They MUST accept Islam as the only true religion
They MUST accept the prophet.
They MUST do as their Imam says

There's a whole lot more MUSTS, with the implied threat of some sort of violent retribution if they don't. So, peace loving or not, they WILL turn on their non muslim neighbours if required.

On the other hand:

Most everyone else....don't MUST anything.
