Philosopher – the amount of things you say that are just wrong are simply disturbing.
Very few Jews had the ability to leave Europe. Where could they have gone? The US, Palestine, and other places were all blocked off to but a few.
Your comparing things to a fantasy about what people had the ability to do to make your point that it was somehow all voluntary and that is what is going on today, is simply intellectual dishonest.
How about a different viewpoint. We can have vaccine mandates and restrictions due to COVID without it taking away rights that result in genocide. The very nature of society is giving up some level of personal freedom so we can live together. You want to make slippery slope arguments, then why not say that laws that make drunk driving illegal is risking going full Nazi. There always has to be a balance and suggesting that any specific restriction you don’t like is somehow dangerous is simply disingenuous. Rather, I would suggest the question is, as it pretty much always has been, what as a society do we accept or not. I am fine with vaccine mandates for one.
