Belligerence does not need to include physical roughness, just like violence and abuse can be verbal (spoken or written) and psychological, not only physical. Defying crew and police requests/instructions/orders, saying I won't get out, threatening to sue, etc. undoubtedly has to qualify as being (verbally) belligerent
Refusal of an unfair request is not belligerence. I know there are law-and-order types who want to believe it is, but we conservatives actually value the individual over the collective, and should relax our law-and-order reflexes when they impinge on our value as individuals.
