Denouncing other people is not a way to create Achdus
thats the point. we dont want achdus with apikorsim. we push them away. their ideology is poison to yidishkeit. if individual members want to do tshuva and come back to torah true Judaism , we will have achdus and take them back with open arms. but the actual group? no way! we push them as far as possible! no achdus with people who deny basic tenets of judaism
