The first gun control laws were actually targeted towards blacks. The constitution was originally drafted to apply for whites of the United States of America. Courts changed this as blacks were only considered 3/4 a person for census purposes.
The current gun control laws are still somewhat related to race, for example, Brady Campaign targets saturday night specials claiming they are marketed towards poor blacks. It's nothing more than an excuse to ban "cheap affordable firearms". The problem is identifying what a saturday night special is? Sure there are cheap crappy handguns out there but some people may even consider Glocks to be saturday night specials, where does one draw the line? And this is why it's bad to allow government to make decisions for us in determining this. They also target so called "assault weapons" claiming they are mainly used by extremeists, terrorists, and neo nazi groups.
I don't think it's purely aimed at race, I think it applies in a small way, but I think the overall goal of gun control is to disarm the decent law abiding citizen because it is easier for government to tell you what to do without a means to resist or fight back while using propaganda and spinning it.
Brady Campaign is launching all kinds of ad's for example, they are claiming that the .50 cal barrett sniper rifle has no legitimate purpose for sporting or hunting purposes. Notice the bold, anti-gun groups claim they are not against guns, just those that are not used for sporting or hunting purposes. This is pure propaganda, these anti gun lobbies try to classify firearms to justify banning them one step at a time. The right to bear arms was NOT written for sporting or hunting purposes, it was written for us to protect ourselves from enemies foreign and domestic. The current campaign the Brady bunch is running is claiming that Barrett sniper rifles can be used by terrorists to shoot down airplanes, they are spinning everything to fit their agenda.
It's all about banning the "evil powerful looking guns", then they will go after the hunting rifles and handguns next.
