It may sound insensitive to say, but the truth is that the loosening of controls against delinquency has led to major cities being inundated with drug users who make public washrooms unclean and feel unsafe.

The belief that it is unethical to set and enforce boundaries on the behavior of people in the lowest rungs of society, to prevent anti-social behavior, has spread like a memetic contagion, leading to societal decline.

You're not wrong, but to be slightly more sensitive, I'll say that a small number of people with serious behavioral problems can ruin it for all the rest who just don't have money.

Where do you live that your city had been “inundated” with public drug users? I live in a major American city with millions of people and this just isn’t true.

Come on man, most major cities suffer from this. San Francisco, Seattle, Chicago, New York City, Philadelphia, Austin, Denver, etc. all have overrun areas in their downtown core with rampant homelessness and public drug use.

The telltale sign is, "do the Starbucks have code locks on the doors?"

I live in Vancouver, Canada and I can confirm it's a severe issue in the downtown core.
