I like the idea that you realize you're potentially beating a dead horse. It must really feel this way when (you may not realize) your entire comment is full of assumptions about 'people who hold views like this' and straw man arguments as a result.

I never dismissed homeless people as insane addicts who can't function in society, and I didn't imply they couldn't be helped (I implied that funding was being cut to institutions that could help, and that's a fact in New York that started under previous mayors).

That's what politics is often reduced to, straw men, and the idea that the argument-maker has 'heard it all before' and therefore is tired of making an effort to make an argument that has facts in it. The truth is, if you think you've heard it all before, that's probably a sign you need to listen more carefully.

In that sense you would have been wasting your breath.
