I need to demonstrate that building emotional safety for a team involves unit cohesion?
No, I don't. Like I said, if you can't see how those two concepts connect, there's nothing here to discuss.
Also for anything I wrote to be an ad hominem, I would have needed to call you a name and also claim that, because you are that name, you are therefore wrong. I did neither, so no ad hominem occurred. There is nothing here for you to be sick of.
You can feel vaguely insulted all you want, but that's got nothing to do with what I wrote.
