I take somewhat of an issue with the premise of this thread. The fact that the RCA tolerated Mr. Weiss’s antics for so many years says more about the RCA than it does about Weiss. In my mind, the RCA will go down in history as the organization that brazenly and idiotically bashed HaGaon HaGadol Rav Ovadya Yosef Ztz”l (http://www.theyeshivaworld.com/coffeeroom/topic/about-the-rca-i-do-shudder) while tolerating, and hence legitimizing, Weiss and his nascent breakaway movement.
But hey, lets at least be glad that at this point Weiss no longer has whatever legitimization RCA membership conferred upon him, and that the RCA doesn’t have the legitimization of being able to say that they washed their hands clean of Weiss and his perverse denomination of so-called Judaism on their own.
