May a Deaf Person be Included for a Minyan?
Question
Someone close to me once told me they chose Reformed Judaism because deaf people were excluded from Orthodox Judaism Minyans and that person thought the Orthodox cruel (the opposite of loving kindness) for excluding them.
SO, the question beckons: Why aren't deaf people accepted/admitted as participants in prayer groups of 10 (Orthodox Minyans)? What in the Torah states clearly that deaf men cannot participate and what is the main, most widely accepted rabbinical opinion for the reasoning? Why not?
