Can someone tell me where in the 2nd amendment it says you can carry machine guns?

[Gawdzilla Sama]

And, again, why should we trust strangers who feel compelled to carry guns when there's no need to do so?

Your trust is not required. I will carry anyway.

BTW "irregardless" is a double negative.

As in "Irregardless of grammar nazis?"

So, you don't trust people, so you carry. Sounds like a crossfire coming down the pike. 

I do appreciate your forthright disregard for the people around you, however. Makes it easier to illustrate why we shouldn't trust you.
