There are certainly a few identifiable patterns.

You do have the deadbeats who've exhausted all legitimate ways to avoid consequences. You see this not just in child support cases, but people who are looking at losing their driver's licenses. They have no legitimate way to wiggle out of the consequences, and they don't accept the consequences, so they will try any Hail Mary crazy play.

Then you've got the slightly smarter cynics. These aren't true believers, but people who intentionally waste time. The plan is to be so frustrating that the court gives up rather than continue to waste resources on a low level case. These people also may be trying to be so frustrating that the judge or cops lash out and do something that actually does violate the person's rights. Just because somebody is obnoxious, they still have rights, which is why judges will sometimes allow these people to go on and on.

Then you've got the people who are naturally contrarian arguers. They'll argue about anything, anywhere, and use the most troll logic possible because all they care about is leaving the other side speechless. This is your Kim Blandino type, who will argue to the point of overturning decisions even when it's in their favor.

Then you've got the gurus. They may or may not be true believers. A lot of them will intentionally get a court case going so that they can spin the results for their followers.

Then at the end, you've got the true believers. They might come sliding in from any of the above categories, or they might just have been grabbed by the notions of Sovcits and run with them.
