Because they are fun!

Submachine guns have many practical uses. They are also plain fun. This man picked one up for the first time in his long life. Like driving a car or riding a bicycle, the pleasure comes from being in control of a well-designed tool. Unlike riding a bike or driving, this pleasure is denied in many states and severely restricted on the federal level…and that’s just wrong.

NFATCA is among the groups trying to reduce the federal and state impositions. So is the NRA-ILA. You can do your part by supporting them, also by educating people around you on the value of modern arms for self-defense and other, more fun uses.
