Including "assault rifles" .... you tell me Magoo.
We've always had semi automatic rifles & pistols in my life time....we've never had mass shootings and killings or the contempt for life we have now.
If those are "straw men" to you, look in the mirror and you'll see a straw man staring back at you...
You must be young, or have selective memory. Semi-automatic weapons known as "assault weapons" were banned by Federal law from 1994 to 2004, but many similar weapons were not banned even then due to quirks in how "assault weapons" were defined in the law, and subsequent redesign actions by gun manufacturers to evade the law made the whole thing moot. Political action by the NRA (heavily influenced by the manufacturers and dealers - have you noticed?) has so far defeated any attempt to extend or renew the ban.
I will withdraw my statement about your straw men if you will describe what exactly it is that you are arguing against.
