Critical thinking is sorely lacking, all around, nowadays, IMHO. And I'm one of those from the left. I try to speak to my people about this, as I hope everyone from every 'side'/perspective does with their political peers. Selective editing and lack of context to manipulate/create a belief and especially emotional reaction (and yes, often in the case of the media outlet, $$) is rampant - and wrong, wherever it's coming from.
