How Far is Too Far?

[Spence]

Rookie official here preparing for my first season.

I'm looking for opinions on how far you let a coach go in his/her complaining?

Are any of the following "too far?"

You suck.
That call sucked.
That was a garbage call.
Are you blind?


Quietly within earshot of no one but me in a non-hostile tone: "Geez, Spence, that was a B.S. call."(without using the initials)

Cursing? Automatic T?

Thoughts?
