I can answer his questions completely. Yes the 2nd amendment affirms my right to own a tank. It even affirm my right to own a nuclear missile. A nuclear bomb would not technically me an arms but a missile would. However the material to make a nuclear armed missile can and is highly restricted as it should be. The 2nd amendment affirms my right to own arms and it does not allow for any form of restriction. There is no exceptions. If something can be deemed an arms I can not be restricted in any way. Regulating or registering are both forms of restrictions and are infringement on my right. Doing background checks for more than just a criminal record is also infringement. An amendment is the only legal way.
