See, this is the part where I lose you. There are many reasons for him to engender this much heat. He could want to change things. Or he could be trying to amplify his voice (as I've heard some Trump supporters actually posit). Or he could be setting up a position that gives him wiggle room (remember that his policy paper on immigration was not a direct reflection of his stump speeches). I don't think you can dismiss these other possibilities so easily.
You know, I try to believe people when they tell me what they want to do. When Iran says it wants to kill me, I believe them. When Trump tells me (in his book) how he negotiates, I believe him. And so far, his campaign is going by the book. And I know that Trump is going to benefit from this deal (he'll get to be President). But what am I going to get (for sure)?
If Trump is willing to cause this much controversy merely for the sake of attention, and/or simply as a cynical gambit to achieve the presidency, but without any real intention on delivering, then yeah, he would be as unsuited (and potentially dangerous) for the office as his detractors claim.
The problem I have with that characterization is it becomes an almost cartoonish parody of itself. Suitable for dramatic entertainment with stock evil characters, but not typical in real life.
Sure, perhaps a Clinton, who has always existed in that state, but Trump who has worked with thousands of people in the private sector? Where are the whispers of a perverted freak? I'm not hearing them. I mean, Obama isn't really evil - he's just a lazy stoner.
