The NRA, with or without Grover Norquist, is the single most effective group championing the rights of gunowners.
If the situation in the Mideast is more important to you than your Constitutional rights, by all means, quit the NRA!
Not trying to get in a flame war here, but I try to buy products and services, for example, from companies who don't force a gay-rights agenda on their employees. (I switched from AT&T for that reason.)
That said, I think the greatest danger to this country is radical Islam. As such, I will not belong to an organization with someone like him on its board. Read the two threads our friend linked. Then, tell me your thoughts.
Have a great day.
