This is even the case when passengers have not really misbehaved, but have made some sort of joke about terrorism or bombs (acting weirdly since it would be clear that in an enhanced security environment, making such jokes is likely to get them into more trouble, as has happened once in a while). But when passengers take actions against cabin crew, there is very little tolerance for such actions and passengers are quickly offloaded. Consider this case where the passengers asked for some seat arrangements that was not possible by the cabin crew, an argument occurs and the passengers throw water on the crew and also throw hot noodles. In the current environment, pilots would typically try to deplane such passengers (link to article):
Chinese authorities vowed to severely punish Chinese travelers who threw hot water and noodles on a Thai flight attendant and threatened to bomb the plane after they became enraged over sitting arrangements. A Chinese passenger berated a crew member of the budget airline Thai AirAsia before pouring hot water and throwing noodles at her during a charter flight to Nanjing last Thursday. The flight returned to Bangkok and the pilot asked the passenger and her entourage of three others to disembark. They were reportedly upset after being told they couldn't sit together and even after a flight attendant helped them change the seats. In footage aired by China's state television CCTV, a male passenger loudly threatened to bomb the plane. He later said the attendant was scalded by accident during a tussle over a bill they had requested for the hot water.
