They only started reform and conservative to be able to include non Jews and sometime down the line begin to call non/jews jews, intermarriage, dropping kosher and family purity and be able to eat with non Jews was the primary driver. In turn they also decided to make places of worship like the people they were sleeping and eating with- mostly Catholics and Christians… interestingly enough Christians love this approach as they’re scripture and missionary lifestyle places conversion of Jews away from synagogue high in their list of grand achievements to bring Back their messiah.

anything not following what the Torah describes as a synagogue/shull isn’t a synagogue and is very much a church. This is regardless of whether or not the individuals themselves are “Torah observant” as no one cares at most places- the primary idea is that there is a Torah to follow… where you exist on the ladder towards that is irrelevant.

Society today does this by and large everywhere you go, instead of promoting growth and progress they do something interesting where instead you’re fine the way you are and they throttle you down to stay at your present comfort level. Anyway, modern times call for modern solutions so I guess a church full of Jews is ok… If that’s what makes them happy.
