2A Doesn't Protect Your Right to Purchase a Firearm; Court

A couple of concerning things I see in the gun control fight that would be outside the usual methods of gun bans and restrictions are the ability for credit card companies or banks to say you can't use your card or funds to purchase guns or ammo. The other, more disturbing, and newest attack is saying the Second Amendment doesn't protect your ability to BUY guns. It only protects your right to have them.
