These concerns are mostly thin veils, and the knee knocking isn't something I can take seriously.
A lot of it is and some of it isn't, but I find that GAF is in general hostile to pressure coming from the left of the democratic mainstream. There's a poster in this thread who rejects the use of the word neo-liberal to refer to anything besides Chicago school economics and also suggests that there is literally no value to be found in reading Marx. Those sorts of attacks on the legitimacy of anything to the left of left-leaning liberals are what I think is really problematic, and I think you see a lot of that sentiment in this thread when collapsing okay posts people don't agree with, with the obvious shitposts.
What we should be discussing is where do we at our level of understanding and information believe funds should go, where do we really need it the most, what's prudent, and how she could be most effective at bankrolling operations.
But that's not nearly as interesting as the anxiety and hardheadedness that leads to "why won't she just go awaaaaaay".
Get us around that hurdle, and we can have a proper discussion.
I agree that's probably a more useful conversation, but I don't think we really get to control political discourse to the level that most people think. Ignoring a conversation isn't always not making a statement in it. I'll grant it's often neccessary though.
I'm more partial to a fairly neutral,"this is a good thing" than the "only bernie-bros have a problem with Hilary" that is fairly common on this topic. Just like I am more partial to the people actually talking about what their problem with Hilary might be instead of knee jerk "lol shillary".
Certainly what you say is valid if we are dealing with a narrow group of voters. We aren't. The Democratic Party is a big tent of voters who represent a large portion of the U.S. populace.
If someone is overwhelmingly popular then that popularity should be able to persist when dealing with what is a large subset of voters (The Democratic Party) which includes many of his most passionate supporters.
Honestly, the best way to describe Bernie's popularity is the old phrase, "The backup QB is the most popular player on the team."
You're only looking at half of the equation there, both the sample is different, and that matters more than you're giving it credit for because that affects turnout on both sides, but also the weighted preferences of people are different. The key is getting someone that the largest number of people, well in the right places anyway, would actually be bothered enough to vote for. I still think this is Hilary, but it's a different argument than you seem to think.
I don't know much about sports but maybe the equivalent analogy is that this QB might be better statistically in the abstract, but against another team the backup QB is actually better because of a specific playstyle/relationship with his team.
Again I think they are giving Bernie too much credit, or more accurately the socialist label, too much credit there, but I don't think it's a fundamentally misguided argument.
