2nd Amendment only defends White Americans. I can assure you, if someone brought up the notion that there should be tighter gun laws... for Muslim-Americans and minorities(in general), the Right Wing Conservatives would probably say, "Yeah, that's a good idea!".
Seriously, don't know how long until the bubble bursts. Even though our eyes have turned towards Muslim extremists since the Paris attack, that never erased all the other shit that's still going down over here against minorities(like that recent police shooting of the guy at the gas station). We ARE fighting a war, but it's not one ONLY against Extreme Muslims, it's a war against EXTREMISTS in general. Islamic Extremists, Extreme Nationalism(so-called "Real Americans"), White Extremists, the fires aren't going to quell until we fight against this hatred on ALL sides, because turning our back on one while we face another isn't helping anyone.
