"A rule of etiquette -- in business, at the dinner table, at the barbershop and elsewhere -- is 'never talk about religion or politics.' These subjects are highly contentious and usually result in heated argument instead of general agreement. 'Never discuss religion or politics with those who hold opinions opposite to yours' has been cited in print since at least 1840. 'Do not discuss politics or religion in general company' is from 1879."

I think we will somehow survive as a society without hearing this dude's thoughts on incest. And yes, I think people would be better served spending their time on hobbies than arguing politics on the Internet.
