If you give these people affordable housing, the result is affordable housing with shit-covered walls, and burnt carpeting drenched in pissThey are as soundly devoted to denying the impact of mental health and addiction issues on homelessness as they are to denying the viability of nuclear power. And I don't know why. I don't get it. At the absolute best attempt at reasoning, they'll maybe tell you that asylums were terrible inhumane places. But so what then, the "solution" is to do nothing? Toss them onto the street, let them starve and suffer and die? As @Tour of Italy said above, their progressivism is all driven by spite, they want the whole world to believe they're morally superior while they treat the homeless like a NIMBY game of hot potato.
What is it with denying mental health as an issue? Any sane homeless person who actually wants and would benefit from being given a leg up with housing support will tell you that for every one of them, there are ten more homeless people who are just despicable, violent drug addicts who actively resist attempts to offer them help. They want to shit up the streets and live like animals because even the bare minimum of responsibility that comes with being a non-violent member of society is too much for them. But they treat politics like hot potato just the same as they do their physical neighborhoods - if it's mental health then the Democrats have to admit there's more complexity to the issue, but if we just say it's all about being priced out then I guess the Republicans are all at fault. Even though this shit only happens in gentrified, hipster leftarded cities that praise themselves for being bluer than an eskimo's balls.
