> Let’s focus on the core issue. Secular Zionism was a highly organized and targeted campaign to destroy Judaism and replace it with a secular national identity.
2nd, I don’t agree with this. Surely, they were anti-religious and often militant, but was this the main focus? The main focus was to organize as many Jews as possible to support their case and join the movement. They had enough non-religious supporters to look for. Were Hashomer Hatzair recruited primarily from yeshivos? I presume mostly among already numerous non-religious and assimilated Jews, who would otherwise become anarchists or communists.
Do you mean already in Israel? Same – majority of population was not religious and Zionists saw religion as a dying entity.
