It's all about power and ego's.
With these particular Hollywood people, their need for power is so high that they have collectively organized to try to discredit and destroy our President because he is a republican. To them, party comes first and the safety and freedom of their country second. This is the ultimate in egotistical thinking and selfishness and some would say possibly treasonist behavior.
I truly believe they are mentally upset that the American people have voted in a President and a Congress that does not support their agenda and views. To them, this means they no longer have any power and it's absolutely killing them! Their Ego's are crushed and they are "acting" out just as children do when hurt.
They live in a false world and their behavior shows they are really out of touch with the real world. I do like the products they sell but, I won't be buying any that these people make!
The sad thing is, they are so wrapped up with their own kind in fantasyland, they probably don't even know how rediculous they have become?
