Joseph:
If for nothing else, thank them for all the learning they supported throughout the years. Even if they would stop supporting right now and never give another agurah, we have no concept of the schar thay have for supporting tens of thousands of Kollel and Beis Medresh men learning.
To Pashuteh Yid & others:
This does not mean one should support the “Zionist” (Socialist) or “Post-Zionist” (American/European/liberal) ideals. We (as Yidden you are Makir tov to all beings, especially other Yidden) just believe in giving credit where it is due.
