It would be insane to your classist bigoted NIMBY ass, but that’s the reason why no one on the left listens to worthless Karens like you anymore.
Being a drug addict or severely mentally ill doesn’t mean you can’t or shouldn’t have a house. Actually, the opposite: people like that need to just be given housing more than a normal person because they can’t take care of themselves, and that means even if they destroy the house, they should have it.
Drug addicts and mentally ill people have rights.
They have rights, and there’s nothing you can do to change that fact. Nothing.
And that means they have the right to housing just like the rest of us do.
You’ll have to live among them whether you want to or not, and you best get over it.
