To respond more directly, I didn't mention any double standards between the US and countries with immoral policies. I'm not even sure what that means; it's a nonsensical statement, as double standards don't exist "between" countries, they only exist in terms of criticism. Specifically, they only exist where criticism is biased.
To your second point, you say the Warsaw Ghetto wasn't able to hold elections to form a democratic government because they "didn't have enough time"? It had absolutely nothing to do with not having enough time. The Ghetto was a transit point for people to be gassed, nothing more. Imagine if they were encouraged to form a democratically elected government and hold elections, like Gaza, and if those elections were backed and monitored by international human rights organizations, like Gaza's elections were. And imagine if what they voted in was a theocratic dictatorship who proudly proclaimed that their winning would signal the final democratic election, ever.
Finally, you might have misunderstood what I said. The Germans in my scenario are the Israelis - that is what the BDS people think. They think the Israelis are Germans, and the Palestinians are Jews. The only irony in the situation is that the people who think this are Germans and/or other Europeans who did not give a flying fuck about the Holocaust when it was happening, and now suddenly are gripped by conscience when one is not happening - insofar as they can still be antisemitic in polite company.
