And a Ba’al Mum can’t Duchen? “
So perhaps I misspoke and it ONLY refers to the Avodah. Same principle, however, even if it turns out I am mistaken about the one specific Avodah (isn’t duchenen part of the general Avodas Kohanim, though?).
We will always find some segment of the population that is precluded from some mitzvah or chiyuv that is incumbernt on others. So are they to be thought somehow discriminated against?
(This whole topic reminds me of the joke of a man who came to a Shul rabbi and told him he would donate $100,000.00 to the shul if the rabbi would make him a Kohein. Naturally the rabbi told him he couldn’t do that. They argued back and forth, with the man upping the ante each time, until the rabbi exasperatedly asked, “But WHY do you want so badly to be a Kohein?” To which the man replied, “Well, my grandfather was a Kohein, my father was a Kohein, so I want to be one, too!”)
