Agreed- a lot of people (on HN at least) are hypersensitive to any suggestion that any homeless people are voluntarily homeless, dangerous to themselves or others, or engage in any activities that everyone living around them would prefer they not engage in.
I get it; acknowledging that can be a slippery slope towards demonizing all homeless people, which in turn could lead to people rationalizing not trying to help the situation, or dealing with it in ways that don't help those in need.
But it's dishonest, and it's a weird sort of virtue signaling to try to shame anyone who says they don't like wading around in syringes and human waste and clearly mentally ill panhandlers when they visit SF. Mass homelessness is absolutely a problem not just for the homeless themselves, but for everyone in a city. There's nothing wrong with saying that mass homelessness makes a city a worse place for everyone, not just the homeless themselves. Accepting that makes it a lot easier to motivate people to actually do things to improve the situation.
Anecdotally, it's an issue where people tend to hold extreme positions with no middle ground- either SF's homeless are primarily noble beings fallen on hard times who need our help, or (the other extreme view) they're primarily panhandlers taking advantage of local sympathies and weather and are fine with sleeping in doorways and pooping in alleys if it means they don't have to have jobs. In reality it's some combination, but I have no idea what the demographics are or if anyone even knows.
If there's no common ground with how people define the problem, there's no agreement on the solution. It sucks but if people don't view it as a huge gray area with multiple valid perspectives, it can't ever get fixed in a meaningful way. People will just continue arguing over whether to arrest them all or throw money at them, and the problem will persist indefinitely. Having said that, I really hope the additional funding approved by voters last week turns out to be a step in the right direction that makes a tangible positive difference for everyone in SF, homeless or not. I have no problem with throwing money at the situation if it actually helps.
