I went and
read the bill. I don't object to anything in it.
There is a section of the state Education statute that requires the governor each year to designate certain days as special and particularly of educational significance. Schools are then encouraged to integrate into the curriculum topics relevant to that date.
While I don't care that Harvey Milk was gay or if students are taught that the gay rights movement in California was a good thing, adding Milk to the list of existing dates does stick out a bit. Currently there are only three such dates:
April 6: California Poppy Day
April 21: John Muir Day
Second Wednesday in May: Teachers Day.
This will add a fourth:
May 22: Harvey Milk Day
So I can see an argument that with such a small list that Milk may not be the first person who should be added, but that is independent of what he did in life.
