What on earth leads you to make such a fallacious statement?
> no choice but to hear it
Sort of. You can wear ear-protection, turn on the music of your headphones, but overall it is arguably a bug of our physiology that we cannot close our ears the same way we can close our eyes.
> If I say to you, “Picture a yellow spot!” you will.
No, not necessarily. Also, this is not because speech is a command, but because we interpret speech automatically. So if I tell you "Whatever you do, do not picture a pink elephant", you will nevertheless think of a pink elephant, counter to the command I gave you.
And of course, if I say "Jump off the bridge", you will probably not do so, because, again, it's not that speech is a command, but that we interpret speech more or less automatically.
Anyway, no idea what any of this has to do with the question of whether speech is violence.

Stereotype much?
