Call me Skipper - Dare I offer you a little bit of advice? (37 years in professional aviation). If I met you at dispatch and you showed signs of the hostility you suggest I would off-load you, shortage or no, one simply doesn't take that kind of **** into the air or down route, it is a flight safety hazard.
It doesn't matter how right you may be and how wrong they may be you must still remain professional and sort your grievance out with those that caused it or allowed it to happen. Your resignation won't bother CX one bit, they will still be there when you retire and your current approach is setting you up for the sack anyway. One day you may be looking for a DEC job yourself, don't answer now but when you have to make the decision, will you turn it down on moral or ethical grounds?
Blast away here on PPRuNe, of course, that is what it is for but be very careful about taking a bad attitude to work, you immediately put yourself in the wrong.
Just advice, that is all.
