But to this, the answer is: every defensive technology can be used as an offensive weapon. I can pack my SAM turrent on a truck and drive all the way to your city, and start shooting down your airliners, and you won't be able to do anything about it, because whatever guns you scavenge from a museum mean nothing to my anti-ballistic vest.
This is what I think of when I see people who purposefully inject themselves into communities, feign offense and call society for help. Using means of protection as weapons.
On the contrary, Chinese martial arts (as well as physical exercise more generally, as with Tai chi chu'an) use the pushing hands exercise to teach how to skillfully yield and redirect the other party's power. It's viewed as foundational to the entire discipline.
There was an episode of STTNG that had a profound effect on me as a kid as a metaphor for confrontation, where the crew of a destroyed ship kept saying "more power to the shields" when the "shields" were actually causing the problem.
A teacher asks some student to stand up and raise his hands before him. The teacher stands in front of him and does the same, touching the students hands. Then the teacher starts pushing, and the student uses force to stay in place. Then the teacher uses more force, and so does the student.
Finally the teacher asks: "Whay are you pushing me?". "Because you were pushing me!"
This is exactly what is happening here. You cannot expect people to give in once you start pushing.
