Germany has an even lower threshold for criticism of Israel and organized Judaism than the US.
Mainland Europe (excluding Germany) is generally way more pro-Palestinian than the US. However that doesn't extend to our institutions. Case in point: Dutch riot police brutally beating up University of Amsterdam students for setting up UCLA/Columbia-style tent blockades.
If you're an American academic or student you can come to Europe and continue both your work and pro-Palestinian activism within the Overton window of mainstream European consensus on the two-state solution. Anything that is more radical than that might get you in the same level of trouble or worse than the US.
Basically Europe is a non-solution for pro-Palestinian American academics and students.
