> Trying again is often not an option.
Life is an iterative game. You fail one day, you pick yourself up and try again the next one. The very act of trying makes you better at it. (For example by having a better internal model of what other people might think of a given text.)
> I know I'm a reasonable or adequate communicator, it's just that I'm not an excellent one.
For whatever it is worth I find what you write perfectly clear.

Oh i see! Controversial subjects be controversial. I don't think aiming for "non-controversialness" is a worthy goal in itself. Of course one should pick their battles, but I wouldn't take that as a sign that there is anything wrong with how you communicate. You are not going to convince everyone, every time about everything. If you could, we would probably call that geas not communication anyway. :)
> They were so good they would spellbind their audiences.
I'm not familiar with the names you mention, but I will check them out. Thank you for the recommendation.
I still think we have spellbinding orators who discuss current public issues. I would count Adam Conover or Jordan Peterson as such for example. (and here I intentionally picked ones ideologically far from each other.) Now of course since I don't know your examples I can't judge how they measure up to them.
