Why do the liberals (including several on this board) continually challenge gun owners to explain and/or defend why they need this or that type of firearm. Let me clue you in, sweethearts. We don't have to defend or explain anything. It is not up law abiding gun owners to prove anything to you. We have the right to own (within some obvious limitations) whatever firearm we want. Rather, it is up to you to explain and/or make a compelling and a Constitutional case why we should not. So far you have not been able to do that. So, please, stop expecting me to explain to you why I "need" an AR-15. What I need or don't need is not your decision to make.
