You are guessing ...
Ok, so, once again, you are just some random dude "having an opinion" with nothing more than prejudices on the subject.
There is a lot of things to say about the mistakes of Germany. And a lot about the mistakes of France, who painted themselves in a corner and is nowadays mentioned as an example to not follow when deploying nuclear. If you apply your own logic, it means that wind and solar is out of question because of Germany, and it means that nuclear is out of question because of France.
(edit: just to be clear, my point is that it is ridiculous to say that the problem of France demonstrates that nuclear is not an option. I'm not saying wing+solar is better than nuclear. I'm just saying that the "Germany argument" is hypocritical, because if you really think it's valid, then you should also be against nuclear)
This ridiculous idea that "a few people on the internet" are the ones in charge of managing the network is just laughable. You are saying "a lot of groups in the US are trying the same". So, what are they doing: they are going to the electricity network owners and are saying "can you give it to me one sec, I don't have any qualifications, but I just want to play with it"? If in US something is changed in the network, it is the results of advanced studies done by very advanced experts. Some expert groups may disagree on strategies, but pretending that idiots who are not even understanding what is happening in Germany will just be able to change things is just ridiculous.
More realistically, the tensions you are talking about are from difference of opinions of two EXPERT groups, but you are just being intellectually dishonest by saying "their idea looks a bit like Germany, so obviously, they are idiots who haven't thought about it".
As you say, decarbonisation needs to happen but we need to think about how. You are not part of the group "thinking about how" if each time you see a plan that superficially looks like Germany, you conclude it can only be "not thought about how".
