They can, but probably shouldn't. The people that "think for themselves" think they know better than doctors....which, like I said, narcissism. It's the main selling point for disgruntled republicans/libertarians/etc. Make the average white guy feel awesome about themselves when they really don't have a whole lot to feel awesome about, preying on their insecurity and lack of achievements.They are only cartoon characters for other people , you are so entrenched in political warfare it's manifested your judgements completely. You're just another one of those winners and losers - divide and conquer manipulated persons. People can think for themselves at the end of the day.
