The affirmative responses here are astoundingly cynical. "Yes, it is Sanders' fault that HRC lost, because many Democratic voters would not have realized how much they disliked her if she had not faced a heavily contested primary against a candidate whom those voters found much more appealing!"
I didn't "realize" some hatred for what Clinton was; honestly, I started hating Clinton due to her being the reason bernie wasn't going to win the nomination.
And why do you think that's generalizable? Political arguments are no substitute for self-reflection, which is what you seem to have needed.
Because I see it among the other Clinton haters on the left. I used myself merely as an example.
