What do you think of ban on disabled kohanim doing sacrifices in this week's parsha? is that discrimination?
I replied: Yes its discrimination per 2009. Lots of Torah rules don't fit 2009 standards.
And this is true: The Torah is full of rules and requirements and presumptions that no longer fit anyone's idea of morality. Slavery is the most famous example. The rules on marriage and rape are others. Though I confess it never occured to me, I must agree the ban on disabled kohanim from participating in the Temple service is another example.
