Constitution says I don’t need a reason to own a gun.
Exactly. Nowhere in the Bill of Rights does it say these rights are protected based on a demonstrated need. Instead, it says these rights are protected. In fact if you read them they don't say what an individual may or may not do - they spell out what the government may not do.
So it is completely irrelevant whether I need my AR and 30 round magazines or not. What I absolutely need is the freedom to own them. With that freedom (and others in the BoR) we are free. Without that freedom we have tyranny. Not tyranny some day when the government does something they've promised never to do (until we were disarmed). But we will in fact have tyranny right here, right now, the moment we surrender the freedoms protected in the BoR.
We have 200+ years of patriots and good, decent Americans sacrificing, fighting, dying to protect our freedoms. Can we sit idly by and let those freedoms go based on the outright lies of the gun grabbers? Of course not. Fight now, your freedoms and liberties are being attacked.
