There's inherent tension in group demonstrations. Typically most people want to peacefully protest but you also have an element of anarchists and hooligans who jump on the bandwagon and counterintuitively do more harm than good for a movement (by turning "regular hard working folk" against the movement due to needless violence and destruction).

That said, I agree with OP, if you're posting in a public forum, don't turn around and then say you expect privacy. The internet is a broadcast medium, in this sense, you can't push the genie back in the bottle once you let it out.

So, if you're going to say provocative things which don't broadcast them and then expect only your followers to pay attention.
