It won't go down like you think it will.
Sure, they will put up some ridiculous bullshit bill in the house which will ban everything including posting pictures of firearms on the Internet... It could pass, but its most likely DOA. Straight confiscation is the line in the sand and I don't think our representatives would be stupid enough to send the nation down that path. Although to be honest I have almost no faith in our "elected leadership".
The real gun confiscation will come in the form of "red flag" laws. These things will sound good on paper, and will be an easier sell to right leaning folks, at least for a compromise.
Of course no one wants firearms in the hands of a mentally unstable person, or someone who is "unfit" to possess a weapon, right? Jeez, don't you remember Sandy Hook?
But when the ministry of truth defines who is mentally unstable, unfit, and encourages comrades in their witch hunt on evil gun owners, then you can be damn sure the establishment is coming for you.
You thought mask Karen's were bad? Wait till you get your guns taken away for flying a Trump flag and talking shit about your government.
We must never allow our government to pass "red flag" or any other infringements on our second amendment rights.
Heed this warning.
It will be some form of creeping confiscation, as you point out.
Biden’s webpage shows (or did show) that he planned to make it illegal for those convicted of misdemeanors involving hate or hate crimes to buy or possess guns. All they have to do then is slowly expand what qualifies as a hate crime. The confiscation may be slow enough to avoid open push back.
Scary.
