As far as I can tell, that bumper sticker ONLY belongs on Islamist cars and camels because the other religions represented are not killing the others and are not agitating to have ‘non-believers’ pay a tax for their nonbelief and assume ‘dhimmitude’.
I'm with you. I honestly wonder what a person is thinking when they put that sticker on their car. What has happened in your life that you could equate the harm done in the name of Islam (in say, the last 50 years) versus anything done by any other group.
