Dear Thefake,
There isn’t what to criticize. Your giving a position to The Enlightenment that it doesn’t care for. (It’s effect on Judaism.) And then blaming what followed on your cause. The truth is, that pre-enlightenment, assimilation was only possible through conversion to Christianity. From the side of the fence alone, assimilation would have been a major factor. Who is to say that it would have been worse without any Enlightenment?
In sum, I think your completely wrong.
