Opinions are dirt cheap. Everyone has numerous opinions which they readily thrust upon others' - sometimes willing but more often, unwilling - minds.

They raise the pitch or volume of their voices, becoming ever more indignant when their opinions are questioned, examined. They ridicule those who reject their opinions. They are convinced that their opinions - theirs and theirs alone - are scientific facts above and beyond reproach.

Therein lies the problem.

Opinions aren't facts. Facts aren't opinions. It is this simple. Confusion arises when the claimants assert that their opinions are facts; situation tenses when the claimants insist that their 'facts' - opinions, rather - are superior and brush aside all evidence that points to the contrary.

Do continue to insist you're right. One day, you'll find out how wrong you're. I hope I'm there when it happens.
