There was a discussion on this with a radio presenter.
They were analysing the user figures of social media (Twitter, FB, Instagram, LinkedIn etc).
That basically a small minority of vocal people take over (especially Twitter) and impose their views. What this does is make people withdraw, keep silent about what they really think and the 'prevailing view' is not representative then. That this is a concerning trend because important debates are not happening because of bullying and intolerance.
This is why for me, it is a point of honesty and integrity to be as tough as nails and stick to my intellectual guns whatever disdain and insults are thrown my way.
There is no way on God's green earth that some leftie will ever sneer or virtue signal me into backing down, because they don't like my stance. That is never going to happen.
What did the social economist Thomas Sowell say? "Virtually no idea is too ridiculous to be accepted, even by very intelligent and highly educated people, if it provides a way for them to feel special and important. Some confuse that feeling with idealism."
and
"Much of the social history of the Western world over the past three decades has involved replacing what worked with what sounded good."
I think Trump/Brexit is a turning point. It has signalled that the silent majority are tired of the liberal left and their morally anointed Big Government delusions.
