As a rule of thumb, never do anything that requires you are armed. Conversely, never do anything because you happen to be armed.
If you have 'fu, too' issues, I'd suggest you resolve them before deciding to leave the house again. That is unless you like paying lawyers lots of money.
Getting an 'attitude' that because you are armed you have the right, ability or stupidity to be confrontational is the last thing you want to contemplate.
