>Germany is already the largest electricity exporter on the planet
This is not relevant, again, unless it would be impractical to install more transmission lines.
>renewable share
Using the wrong statistic is not a good comparison, what matters is the fraction of fossil fuels. The classification of "renewables" here is crafted to specifically exclude nuclear while for some absurd reason permitting hydropower (which is terrible for river ecosystems).
If you invent a metric specifically to support your ideology, it supports your ideology. However, it doesn't convince anyone who is paying attention to the facts.
>it's extremely questionable how Germany gets constantly blamed
It's not Germany that is truly to blame. It's the anti-nuclear movement which is to blame, and Germany is just one of its many victims. However, this movement led Germany to make bad decisions recently, and those decisions can be criticized specifically, regardless of what else was done.
