I agree. The excessively politically correct are exactly that, the thin skinned that are doing little more than looking to be offended to take advantage of, and leverage, their protected class status to punish those with whom they disagree.
In order to maintain free speech for everyone, you have to have enough wherewithal to ignore the free speech that you don't like, and this is where all this excessive politically over-correct fail.
Of course the Chief should be allowed to hand out his book )off work hours), the same way that those he offers it to have the freedom to decline to accept it, and the same way that there better not be any repercussions for either accepting or declining to take the book.
"Wait until organizations that support incest, or polygamy, or bestiality are shrieking and calling for some official's head because he dared to bruise their precious feelings by calling their sexual practices immoral."
I figure it can't be far off now. Seems like it's just around the corner, before even Obama is out of office. I'd add NAMBLA to that list as well.
I disagree with this.
"your boss can fire you at any time"
True, as most states in the nation have an 'at will' employment policy. You work there at your will, and at the boss' will. Either can terminate employment at a moment's notice. It's not related to constitutional rights, as far as I understand.
If you start handing out materials, any materials, that the boss doesn't want handed out, he can ask you to stop. If you don't, he can fire you for not following direction. Not because you are handing out stuff, and especially not that you might discriminate against someone else. Have to actually have done it before you can be fired for that.
