jackk, when there is a consistent reaction to current events with “BUT remember”, it is not a reflection of interest in Jewish history, but political support of the attackers.
And history is full of cases where such justification is used for a new attack, such as Germans justifying actions against Jews by a reference to Jews participating in 1918 revolution; attack against Poles by cases of Polish attacks against German civilians. See a recent 2015 book “The German war” by Nicholas Stargardt who brings together diaries and letters from that time.
