Well. If you have no problem with threats of violence against people based on their clothing choice - not even people who are naked, but simply people who are fully dressed, except that their clothing exposes - not any naked body parts, but another article of clothing - carry on then.
Threats of eventual violence on locality enacted standards of behavior. Not a problem.
We're gonna bruise and bloody you and toss you out of town for saggy pants. A problem.
We're going to fine you, give a chance to rectify the disrespectful behavior and will eventually put you in jail if you don't pay the fine (which may involve bruising and bloodying you if you resist) is fine.
Again, that's what government does. Don't like those rules? Leave Collinsville. Wow, ONEROUS problem there.
