It creates a gigantic issue for law abiding citizens. This reason alone I suspect will be a source of massive and hopefully effective push back.
Millions upon millions of civilians, hundreds of manufacturers and business have a lot at stake here.
If these changes are proposed, I speculate it will not get through as easily as some others have.
And how many BLM protesters did I see toting AR pistols?
[EDIT] Point being I think the Dems are going to see their own push back as well.
