You just don’t want to see all those irritating news items. The ones that are making you angry because of their stupidity and their lack of understanding what is true and right.
Have an intelligent filter built into the news app (or Facebook) that you tell all your biases to. You teach the filter what irritates you politically, morally and any other conceptual subject of irritation. The filter should be intelligent enough to understand the content of the news and not show it if it is deemed irritating for you.
As an experiment to see how people react.
Crawl (using multiple and changing account) social networks and blogs for comments that seem to be by trolls. Analyze the comment and using similar but opposite words (like antonyms) answer the comment and try and elicit a reaction. Follow the conversation or flame war that ensues. List these conversations on a central site for all to see.
