I guess it's a good thing I never said any of the words you both put in my mouth and "quoted". Not once did I say I know what's best for them. Not once did I say they couldn't make decisions for themselves. What I DID say is that it's ridiculous to pretend that propaganda doesn't affect people IN unions. Which is EXACTLY what you implied.
Don't be disingenuous, "they don't know what's best for them the way I do" is a very fair representation of your words. Maybe you do? If you're going to take that position, own it.
In my opinion what's disingenuous is to ignore the main point in favor of picking some nit.
"My interpretation is objective reality, but your interpretation is dumb". How about don't be an asshole, man?
Is it patronizing to say that workers who respond to threats like this:

might not be making the best risk/reward trade off?
The employer is hardly going to tell you if they're making an empty threat and the prospect of losing your job because they pulled the nuclear option is probably quite terrifying.
Honestly, it's rather patronizing to say that union members who disapprove of their union and want to decertify or deauthorize it must either be ignorant or under the influence of external propaganda or FUD. Maybe they have access to information you don't? Or maybe they just have a different set of values from you? Maybe they hold different priorities from what you hold? Maybe they should be assumed to have their own agency?
I'm not going to say that democracy is infallible - in fact, I'm usually the first to point out the exact opposite. But "they don't know what's best for them the way I do" is a pretty dangerous line of reasoning to start heading down.
