You are correct that veterans are supposed to be upright citizens and models of society but what happens when the civilian normalcy is not what the constitution you specified describes?
I don't have a problem with your thinking LTCH is unfair, just with your actions. You say that a LTCH is too expensive and unfair so you plan on breaking the law by ccing and if you get caught then you will challenge the constitutionality of the law. That sounds like the sort of rationalization that any criminal could use to take something that they can't afford to buy.
If you really want to be the test case then you need to either file a suit that says your are being "chilled" from exercising your rights or you need to go get arrested and defend your case.
The people you listed above like Rosa Parks and Gandhi all openly defied the law and challenged the system. You are just breaking the law and preparing a defense in case you get caught.
