Subjective I grant you that.
Accusations of treason aren't that subjective when there are laws that clearly state what constitutes treason, people who spend their lives interpreting said laws, and probably a boatload of cases to back it all up. When so many sub-comitees (some of them headed by Republicans, apparently) say you can't be accused of treason... well, really people can believe what they want, but then again some think the planet is flat.
Yeah, they dropped the ball. Again, shit happens. When you wage war, your side is also going to take casualties from time to time. As I see it, the deaths are of course unfortunate and shouldn't have happened, but the Americans played with fire and got burned by placing a CIA outpost so close to an ''embassy''.
As for the rest, well there are your opinions and it's fine, but again that's nowhere near grounds to accuse someone of treason. You disagree with her foreign policy, fair enough, I can see why even I don't share your views. I disagreed with Stephen Harper's foreign policy when he was Prime Minister (a lot, at that) but that doesn't mean he was a traitor. Had I been an American, I would definitely had descended in the streets to protest against the stupid and pointless invasion of Irak by Bush, but it wouldn't have made him a criminal.
That's the entire deal with Hilary's past. Her opponents aren't content to vehemently disagree, no. They must wave the whole ''treason!!'' flag as if this was Warhammer 40K or some shit. And on my end, that only diminishes the arguments against her, when dislike and disagreement is taken to such nonsensically hyperbolic levels that it starts to look like mob justice. As much as Trump also gets hit with plenty of stupid accusations, at least few people seem to think he should be jailed on no legal basis.
