That's all they're looking for, too. Time after time we see them exclusively seek out confirmation bias to a particular belief. The funny part is that often times it backfires because they're retarded and Google for headlines for something and present that as their "See!? I was right!" But once you read their own article it completely contradicts the headline — as they frequently manipulatively do — and only reinforces exactly what you were saying to begin with.
There are some people who will simply never be reached. They're either too stupid or too far down the rabbithole that it would take some completely world altering event to change their mind. Even then many of them have egos so fragile that they'd never admit to being wrong.
