I just questioned how he thought that the situation in San Francisco represented how all cities would look if they too became "progressive".
You are treating the topic a bit more in depth, and that is appreciated. But I am still not seeing the case that "progressiveness" on a nationwide basis leads to San Francisco's problems on a nationwide basis.
I glean from your post that you believe enforcing laws more rigorously would help clean up messes like that. That could be, and it's certainly a reasonable argument. But that leads to the question, what happens if everyone does that? Do the homeless then just go to jail? If vagrancy laws are strictly enforced, then where do the homeless go? If needle exchange programs are canned, do the homeless stop using drugs, or do they just die from dirty needles? I certainly agree on "indecent exposure". I'm not sure why "progressives" are in favor of that.
