Unfortunately, our laws and system of justice has this thing called "innocent until proven guilty". Where is your proof?  Are you relying on the word of someone thought to be connected with Russian intelligence?  When did you decide that was a good idea, a trustworthy source?  Isn't that the problem that we have with folks connected with the Russian government, that they lie?  

"Open to collusion"?  Are thoughts alone now crimes?  How do you plan to prosecute a thought without proven action?

"they aided the adversary" - who aided what adversary?  Let's see, Hillary was Trump's adversary - he aided her?  Who is Russia's adversary?  The US?  So Trump aided the US? 

EVEN IF some folder was passed to Trump Jr at that meeting, what was in it?  What nefarious schemes of Hillary's relating to her dealings with the Russians were outed by the Trump campaign as a result?  You can suspect all you want.  But until you have actual evidence, you are just another person with an opiniond
