Yep, you either fight the corruption or you implicitly approve it. He implicitly approves it. He will attack Trump in a NY minute, but has he said anything about the Hollywood or Democrats (i.e. Clinton's and Obama's) entanglement with Weinstein. Nope, and he won't because he believes that a large part of Apple's future depends on Hollywood. He puts money and success ahead of principle just like every other Tech Company CEO, but he does want you to think otherwise.
Well, and he also lives in the Bay Area, and has personal reasons for political leanings. I've known pretty conservative people who, after a decade in the Bay Area, became what we think of as the typical liberal, even to an extreme extent.
And, while it's probably good to have one's views challenged, correct some stereotypes, and move some on positions as one matures, the Bay Area is an echo-chamber pretty hard to resist unless you've got some really principled undergirding.
Your right about Democrats and Republicans, excluding Trump, I see no real difference in behavior. There maybe a handful of politicians that are not corrupt and I allow that they might be either Republican or Democrat I am sure Trump is corrupt, but at this point in his life he is more interested in building America, than building his personal fortune.
Yes, especially in terms of corruption. There is little difference. But, it even goes beyond that. Aside from some pet ideologies and interests, there really isn't that much difference between the two camps on some pretty big things (economics, foreign policy, corporate and special interests). You can especially see this if you watch what is going on in Congress.
A great podcast is Congressional Dish (note: the host is fairly liberal-'progressive' but the info is quite good... you just may/may not agree with her takes on what's good or bad.) If you can listen to a few episodes and not come away enraged, no matter which party you affiliate with, I'd be surprised.
What is typically ignored and the main thing to learn from the Hollywood corruption is that because someone talks like they believe in "good principles, equality, giving everyone a fair chance" does not mean they behave that way. But we know that talking about this stuff is just a cover with both Democrats and Hollywood. Cook is or wants to be in bed with both, so he has to believe the same things. He started attacking Trump before he even met him, based only on fake news distributed by the Democrat machine. He has demonstrated that he is an ideologue, facts don't matter.
Yes, while I'm happy to admit I don't think Trump is a very good person, nor do I agree with some of his decisions... you have to recognize what the alternative was. I've never seen this level of hatred, disrespect, etc. towards any other politician. I really, really dislike Hillary, but if she has won, I (and hopefully other conservatives) wouldn't have reacted like the 'Left' is reacting towards Trump. And, I hate that I often have to defend someone I didn't even vote for (Trump) because he's being so maligned by the media and pop-Left. My gosh, he does enough stupid stuff... you don't have to make up things about him.
