Wrong is a moral judgment. For Manny it was the right time and he will face the consequences, e.g., loss of pay, lack of gigs, etc. I applaud him for his principled stance and courage.
We had a few people in our history who expressed their disagreement at the "wrong time" who stated, "we mutually pledge to each other our Lives, our Fortunes, and our sacred Honor." Many of them lost their lives and fortunes, but they retained their honor.
If he loses any gigs, he is victim of political harassment and can sue.
