Public ridicule of someone who harms nobody but knows not what they do to themselves is maybe a little unfair. Virtually everyone has written stupid things on Facebook... if nobody gets hurt, be a bit forgiving
...except it's not just on facebook, having a companies' house registered company and a website seems a little more than just the odd FB comment.
“Criticism is something we can avoid easily by saying nothing, doing nothing, and being nothing.”
– Aristotle
