There's a grand total of two countries in Europe (Hungary and Greece) where openly anti-Semitic parties hold seats in parliament. That's a far too high number, as are the number of seats those parties hold in their respective countries, but it doesn't probably show that all of Europe isn't some raging hotbed of anti-Semitism.
But wouldn't you agree, BRTD (and, unlike the rest of this post, I'm speaking to you non-sarcastically), that "anti-Semitic parties hold seats in parliament" is a catastrophic level of anti-Semitism, and that people might feel threatened before discrimination reaches that level?
But this isn't about Jews moving from Hungary or Greece.
