“Nobody prays to angels.
Regarding Machnisei Rachamim, for those that say this piece, it is asking the angels to do their job, so to speak.”
You is far less convincing than the academics who say that the Torah is from God but not really written until the time of Ezra! Machnisei Rachamim is a prayer directed towards angels and there is no way to get around it. I won’t say it and neither should anyone else who thinks that Rambam’s principles constitute the basics of normative rabbinic Judaism.
