I would take issue with one thing: We should not have to argue that we need AR-15s. The Right is to keep and bear them period, not to keep and bear them if we can prove that we need to.
However, he is right. Had those store owners during the King riots not had AR-15-like firearms, they would not have been able to defend their stores from total destruction.
He chose America because we have Liberty. I hope we don't lose it while he is here. That is a worse crime than taking my Liberty, the Liberty I was born into. It is twice as horrific to take the Liberty of one who risked it all to choose that Liberty.
