little emotional there Mensaboy,
If you do turn up to work fatigued, then you contravene the FOM, and common sense. Blaming a crew schedular behind a desk for any mistake we make at work (and trying to get away with it) is stretching the bow a little too far.
Some flight deck have been taking leave with out pay. It just wasn't advertised, but l get your point.
Unfortunately those you speak of do exist in the pilot group. I have flown and shared cars with colleagues that do nothing short of make me cringe with some of their antics and over self-belief. And l believe this minority have induced the email from TCAS.
You are correct about rest and politeness when dealing with roster changes.
