So Trump Jr. was under the impression that the Russian government was trying to support his father, and it didn't set off any warning bells with him. He apparently relished the idea of getting support from the Russians.
Doesn't this disturb anyone? Do we really want our Presidential candidate teams looking for and accepting help from foreign governments, especially ones we are in conflict with?
I'm sorry it's not disturbing in the slightest. If someone claims to have dirt on a rival candidate, including "incriminating" evidence, I would be shocked if they didn't agree to hear that person out. You're suggesting that if it comes from the Russian government, it's unethical to use or reveal incriminating evidence about a rival? Just meeting with him and listening to his words is treasonous is it?
So if Putin hands Trump Jr. a memo proving that Hillary committed fraud or murdered someone for example, he'd be the "unethical" one if he revealed it? 
I know I know - Putin is evil and anyone touched by this Mephistopholis even directly can't help but be corrupted. But by the way, maybe I missed something, but when was this declaration of war on Russia? For how many years has this "conflict" been going on? How long has the war been waged and how many casualties have there been?
Here's the difference, jasonr.
Why go through Trump, Jr.?

Think about it. You have damaging information on a candidate that you oppose. It's good information; it's been vetted; it's confirmed true. So why not just publish that information? What's stopping you? You still get the information out. You still damage the candidate you're against.
So why offer it to the opposing candidate (through his son) first? What can you
possibly gain from that?
There are only two things I can think of. Money and/or influence. He'll either pay you for it, or he will owe you. And by offering it first, you can set the terms, or else refuse to give the info or publish it.
By offering it first to Trump, Jr., the person was either trying to get money or to influence the candidate, the one who became President. And the info came from, according to the e-mail that Trump, Jr. got, "part of Russia and its government support of Trump." And the Russian government doesn't need his money (no matter how rich he is).
To which Trump, Jr. said, "I love it"!
He loved the idea of owing Russia for the information. And he asked Jared and Manafort along to witness the deal.
I'm sorry you're not disturbed in the slightest. Russia may not be our enemy, but they are by no stretch of the imagination our friends and ally. So I don't see why you wouldn't be disturbed at the idea that they wanted the President to "owe them one." To
personally "owe them one." And that Trump, Jr. jumped gleefully to take that gift.
Republicans were outraged--
outraged--that Clinton took money from China (although it was given back). Why? What possible reason should anyone be the slightest disturbed that the President's campaign took a few measly bucks from China. Unless we wanted to prevent the President from "owing them one."
Be disturbed, by this, and by the people who are telling you not to be disturbed.
