If you are for public transport and walkable cities, you must be against tolerance for the lowlifes that make people retreat into private transportation for their own safety.

Not really. Their game is to coerce people into giving up their private transportation, so there's no need to solve the lowlife problem. The people pushing this will be exempt from having to live in the hellhole they created as usual. That's why busing illegals to blue cities was a genius move. It's amazing how quickly things change when the people causing the problem can't push the consequences onto everyone else.
