That's word for word what mods write into people's ban msgs. Cool, let's get me banned then.
I have not conducted a study to prove causation of 'Europe (exemplified by Germany & France) become(s) increasingly unsafe for the Jewish population due mostly to the Muslim population'. This is neither the place, nor do I have the resources & expertise to conduct such a study.
Instead, we can derive causality from the growing number of antisemitic incidents and an increasing number of Jews leaving France:

Furthermore we can derive said causality
from French Muslims, Islamists and Islamic terrorists, unlike in any other country except for Israel, specifically targeting Jews in terrorist attacks and widely publicized acts of racist violence and murder.
We also know from studies which I quoted above that Muslims disproportionately harbor antisemitic views and in case of Germany are also responsible for a disproportionate majority of antisemitic violence.
Given this data and the studies I can deduce that there is a causality between Jews feeling increasingly unsafe due to rising antisemitism, antisemitic violence, Jews increasingly leaving Europe (France) AND Muslims disproportionately harboring antisemitic views while also disproportionately being responsible for violence against Jews (a claim which I can only make for Germany).
If this deduction does not meet your scientific merit then so be it.
Edit: I would also address this in a separate thread and offer a more detailed criticism of your statements if I had the privileges to do so.
