I know the context is about Jews and Muslims, but I can debunk the coexist sticker fairly efficiently from a Christian perspective.
C - Islamists - want to kill Christians
O - Peace Sign - want to tolerate those who kill Christians
E - Sexual Immorality and Abortion - want to disenfranchise Christians
X - Jews - literally crucified Jesus
I - Pagans - spent hundreds of years killing Christians and then infested the church with bad ideas
S - Easterners - still infesting the church with their bad ideas
T - Christians - notice how we're dead last
When a liberal says coexist, they really mean comply.
