"Your first claim requires far more evidence."
"In western countries it runs around 10 to 40% support the Jihad."
Pew research polling backs my statement with this poll:
There are other polls showing similar numbers as Germany Muslim statistics about 10 to 15% support of the Jihad in the US. It is a much higher figure that actually support the Jihad through Zakat knowingly or unknowingly.
Yes you are exactly right the issue here is about doctrine not the character of the individual.
In other words once a person believes all other religions must submit, be enslaved or die then it becomes 'good character' to carry out what is needed to be done
Even if we assume that such polls are valid (a questionable assumption), it appears that majorities and pluralities say that violence is never justified. Moreover, you have no data at all from the United States, where I suspect violence would be rejected by even larger numbers.
There were plenty of Irish Catholics (and their American supporters) who believed it was right to kill and die for their religious and political cause. And yet, we don’t apply the broad brush to that religious group.
