>Anti-social behavior can be trivially defined by a kind of categorical imperative. That is: does this behavior, if universalized, render the public service non-functional. It is increasingly naive to consider these concerns simply in a cultural context or some power dynamic.
Your own policy is anti-social then.
If we universalized your suggested policy of having strict(er?) prevention and/or (probably and) enforcement against "anti-social" (whatever that dog whistle means) behavior we would have the war on drugs but for every issue and policy area. We'd be living in more of a dystopia than we already are. The government would be subjugating us (more than it already is) rather than serving us (not that it does this much already). I think any honest assessment based on any degree of standard western/liberal (small L) assumptions about society and government would consider that "non functional".
Do we need a war on drugs? I don’t think so. We just need a war on people making services unpleasant.
Asking someone to leave a subway platform because they are not using the public transportation system for transportation is not a war on drugs. It’s just making people exit a subway station.
