Mercedmike... 90% of those type of those posts are with malice aforethought, its just a question of how much malice (as well as how much lipstick they put on their pig for "camouflage").
The other 10% have genuinely good intentions, and either clarify and/or apologise for how their words were (mis)interpreted.
I, for one, am starting to have a very low tolerance for "board bullies", and will call them out from now on. This is starting to get old. There is NO WAY that the quote in question can be seen as anything but a jab... and to further add, I think teachers deserve a little more respect than that. Just because youre an educator, it does not mean you have to be "on" 24/7.
I dont post what I do for a living, and where I live, because BBs have dandelions among the roses.
