Is it just me or have others here noticed that muslims have a bond with each other via their religion that often supersedes older bonds they may have formed with non-muslims, by way of friendship, association etc.
When 2 muslims meet for the first time, they instantly connect in some way, that people from other religions never do.
That is the general rule of thumb, although there are exceptions to the above statements, of course.
No other religion I know, short of cults, reaches into the soul of the follower and gets such a stronghold of them.
