Input: Poster: Sen.Feinstein foolishly says we need to ban assault rifles because gangs use them to kill police.Gang members are CRIMINALS who ignore laws!  Responser: Deb, you're not worthy of a reply. Conversing with you is like talking to a brick wall. Oops! I apologize for insulting the brick wall. Keep blocking those who present opinions opposite yours. After all, regressives like you live in a world that can't handle the truth.
