ROB, I am sorry to repeat it,but if you learn more Gemorah and Poskim you’ll see that many of the things you think of as mili de’alma are not that — there are Halachos and Hashhkofos about them. Do you really think that election of a Chief Rabbi who is going to pasken shailos and supervise marriages, kashrus, mikvaos etc. is in mili de’alma categery? Are you saying this with a straight face?
Secondly, I do not believe Poskim are infallible, but I also think it is wrong for a layman or half-layman to reject their opinion casually because he doesn’t like it (without very solid proofs).
