> I AM saying "people don't want ride trains that allow 5% of the riders to smoke cigarettes on enclosed train platforms and in enclosed train cars."

Just don't allow that then?

> Public transit advocates need to be honest with themselves that anti-social behavioral issues really matter to people. People are willing to pay more to have a more pleasant experience. When a transit system fails to meet that standard, then you'll suddenly find yourself with a transit system that people don't want to use.

"we can't have good transit because a few people who call themselves transit advocates have bad opinions" is very defeatist. Weak-spined politicians find it much easier to just set money on fire than actually solving problems, so even though most transit advocacy groups in the US emphasize quality and being less wasteful with budgets, your politicians usually prefer the worse options.
