To illustrate:

No, Nigs, it suggests that there are those whose opinions differ from yours - are you trying to stifle opinions which differ from your own?
No, backwardsman, I am already aware that there are opinions contrary to my own.

There are enough unsupported opinions on here, without trying to appeal to a 'higher authority' and thinking that Facebook is it.
