Morons abound. Hope she's fired--can't imagine anyone supporting her, even her family but from the text of the link above I see that isn't the case. Not surprised ACLU took her side either.
Freedom of speech tho, in regards to her employer firing her, doesn't enter into the picture. Those who think it does are simply mis-informed.
The 1st Amendment is very straightforward, and applies only to what GOVERNMENT (congress and it's sub legislation bodies (state govts) cannot do.
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
Again, the founding fathers recognized full well that there could and always would be non-judicial reprecussions from slander, insult, libel etc, that not everything of that nature is protected speech, and 2 of the most famous writers of the constitution dueled over words said and printed in newspapers of the day. Sitting Vice-President Aaron Burr shot and killed Alexander Hamilton.
So, unless her employer is Congress and they (congress) fire her, she doesn't have a sorry leg to stand on in that regard.
I will not put my thoughts into words other than that, but I would hope that God Almighty has a special place in hades for those like her.
