Apparently there's a misimpression among the primitives that governmental employees are free to speak their minds, more so than private-enterprise employees.
I'm not sure.
I worked for the Nebraska Department of Health during much of Bob Kerrey's single gubernatorial term, and I must say free speech was not tolerated in that Democrat administration.
In fact, that's proven the most restrictive conditions I've ever worked under. Even Immigration & Naturalization under Bill Clinton, while antagonist towards free speech, tolerated more of it, than was tolerated there.
And among private-enterprise employers, I've been free to speak my mind--always aware at the same time that free speech has consequences, some of which one may not like.
Too bad for the primitives.
