Fake Information

People who smoke usually know that smoking might prematurely kill them. Or if not kill, then give them cancer, stroke, heart disease, lung disease and etc. People who drink alcohol are aware that they will have liver problems and might prematurely die. Eating processed food leads to obesity which in turns might lead to cardiovascular disease. Its all known, its hard to argue with it, the data is there (look at sources in NHS, WHO, CDC). But very few people know that internet damages your brain.

We've come a long way thanks to controversial opinions being expressed. We've created a more equal society in terms of race and gender differences. Our society is more individualist today than ever before; we allow people to express themselves without excluding them from society. We are still far from perfect, but thanks to controversial opinions and tolerance - we've reached a lot. I'd even say - too much.
