If that is true, then why are antisemitic incidents up across the board in other liberal Western countries?
In Canada, antisemitic incidents in 2017 were at an all time high.
In the UK, antisemitic incidents in 2017 were also at an all time high.
In Australia, antisemitic incidents were up 10% compared to 2016.
In France, antisemitic incidents were up 69% this year so far.
In Germany , antisemitic incidents have been rising as well.
