Dear Ujm,
You understand my family wrong. They are all well to the right of MO.
None of Frankel’s opponents called him a heretic. They said his theories could be interpreted as heretical, and demanded a clear statement in support of the revelation.
Many staunch supporters of Orthodoxy used his theories. Haleivi uses him more than he uses Hirsch.
If Frankel is the founding figure of CJ, than all the more so that Hirsch must be the originator of today’s MO. That shatters your notion that CJ came from MO.
