Not every slope is this slippery. You can allow a bunch of things, but have boundaries for what is allowed on your platform.
A bar owner can kick out a troublemaker, and people won't think "first they kick Shitstarter Steve, and next thing you know they kick you out because you order the wrong beer". Other patrons are relieved that Steve will have to start shit somewhere else.

It's fine to show some people the door.
