Dear Ujm,
The RCA was not happy to keep him. The issue was that he wasn’t the only member who they wished they didn’t have to deal with. Just expelling him would have been declared as implicit approval of everyone else. It is pretty clear where the RCA draws the line on orthodoxy, and they have made enough statements on the issues without singling out names. You are reading into this what you want to be true. It is not the stance of the RCA.
I’m not in denial of the monetary and political influence the more extreme factions holds over the larger organizations. But that is universal. And it takes strong leadership to overcome it. It is not at all a yardstick to measure the personal views of it’s members.
Personally, I prefer the RCA’s approach. Agudah was no more than press release. It didn’t serve any purpose than white washing themselves. The Yated and Cross Currents did nothing constructive either. Stroking your own ego is not the same thing as taking a stand for the Torah.
