Should there be public drinking of beer? Public nudity? Public urination? Public displays of affection?
Should women always have their heads covered while in public? What about men? Should we ban male circumcision until the male is old enough to make the decision for himself? Should we have the draft? What about mandatory civil service?
Do you believe in mandatory bussing? Separate but equal? Co-ed schools or sex segregated schools? State income tax or not? Legalized gambling? What if it's only controlled by the state? Should alcohol sales only be done by the state, or can any place sell vodka? What about beer? Should alcohol sales be prohibited within a certain distance of schools? Are exceptions allowed?
Do vaccines cause autism? Was the Earth created less than 10,000 years ago? Can you petition the Lord with prayer? Is the Pope God's representative on Earth, or the anti-Christ? Should non-believers be taxed at a higher rate than believers?
Should I go on? All of these are controversial. If you have views one way or the other, then your views will be controversial at least to some, if not to most. And if you have no views on a topic then that itself can be controversial. As the morbid joke goes, during the height of the Troubles in Ireland: "yes, but are you a Catholic Jew or a Protestant Jew"?
If everyone has controversial views, then of course they are precondition for being a visionary. They are also a precondition for not being a visionary. Name one famous (so I have a chance of knowing something about that person) non-visionary who did not have controversial views.
But first, name a controversial view of the founder of Lego ... who is definitely described as a visionary.
