It's a pretty slippery slope, isn't it?!
My guess is this is a nothing burger, but maybe a story created to get certain people to freak out.
It's 100% part and parcel with this admin- they're going to get the left to defend 2A for the lulz.
Even with a mental health diagnosis you can still own a firearm. IIRC, the only limitations is if you've been found mentally incompetent by a court or involuntarily committed to an institution.
What's next? Can't buy a firearm if you've got depression or PTSD?
Exactly correct. I have a service-limiting condition/medically retired for PTSD. Sooooooo...???
The other thing at play here is a bit more culturally/politically oriented and something I have evolved on over recent history.
The hand-wringing refrain is always "be careful, setting a precedent they can use against you in the future." I get it, now let me tell you how that's retarded.
They (marxist ideologues on the left)
are going to do it whether you set the precedent or not, the only thing that matters is who gets there first. Given the authority, the left will 100% take your 2A rights, citing any mass shooting and emotional event they want. They'll pass legislation to put you on a list via your credit card for purchasing guns. They'll weaponize the ATF to show up at your house (and probably shoot your dog) to "just have a conversation" about some piece of equipment they unilaterally deem "unlawful" for you to have.
This applies broadly, to everything. Gay rights? The right just wanted to be left alone. Wanna get married? Fine. Don't wanna set a weird precedent!... then the Supreme Court concocts some BS out of whole cloth and makes national law from the bench. And now LGBTQ are protected classes of people, and making memes about them gets you jail time evereywhere without an armed population. Weaponizing the DOJ? GASP! We can't be a banana republic where we prosecute politicians... here, says the left- catch these felonies and let's get an armed tactical team to raid your house on trumped up (see what I did there) charges for the sole purpose of keeping you out of the election.
To think that the left won't do this when they're in power is being purposefully obtuse to history and the actions of the left forever. They don't care about principle, they don't care about precedent, they care about power. That's it.
So the little ethical dilemma is thus- do you support the right in weidling power in the same way, or do you adhere to "muh principles" while the alligator eats you from the feet up?
Remember in the Matrix where Cypher didn't want to see the real world anymore, and was willing to betray humanity to go back in, knowing nothing of what the world was anymore? I think about that a lot.
