Basmelechpenim: People like Dassyochid were taught from birth to hate Zionists. It is their Torah. No one is going to change that ever. This is what they learn in school. They actually have tests about it in school. (I saw the test).
Nothing you will say is going to change that. It will be more beneficial for all sides to concentrate on loving your fellow Jew, regardless of your differences.
If what you are so passionate about is bringing all Jews to Eretz Yisrael, and Moshiach, then do yourself a favor and leave it alone. Talk about something you can agree on.
