With understandable opposition to ideological Zionists, was there a specific point on insisting that they do not go to EY? Same people will lead irreligious life in other countries and be a cause of trouble for those communities.
There could be a purist view that we want to keep EY populated by tzadikim only, and the rest can go to South America, but I don’t think this was a majority view. So, otherwise, we have an issue of Torah v. modern ideologies, but no specific reason to object Zionist settling davka in EY.
