you cited in your posting and, nedless to say, I was quite surprised. How are Rabbi's responsa on sex changes viewed in the Orthodox and ultra-Orthodox (haredi) communities in Israel? If the webpage has cited the responsa correctly, there should be no objection to sex changes and marriages resulting from them, and the Reform Movement has merely adopted Orthodox psak.
