Most problems can be solved by raising the level of discussion.
"Nuclear energy is bad" = slogan.
"How many people got injured/died in the history of normal (meaning, excluding Chernobyl) nuclear vs coal power generation industries?" = real question.
(Actually, nuclear is safer and cleaner and these days, even cheaper in some markets, than coal.)
"Tax the rich" = slogan.
"What's the effect of high taxes on the economy, especially given the mixed taxation code with blurred lines between corp. taxes and small businesses filing 'personal' taxes?" = real question.
And so on....
