If you choose to yammer about "creeping sharia," then you would be better served to choose your targets more carefully, lest you discredit your entire effort.
And if a bank chooses to engage in sharia-compliant banking, remains profitable, and even drives other non sharia-compliant banks out of business, then we have a larger problem.
Your name suits you perfectly I will do what I think is best, and that is not make excuses as Islam slowly gains power here. Not having your approval is no big deal and this is just another step forward for them.
