If religions of staff & students are to be made known by
schools having religious ceremonies with non-believers
noticeably abstaining, this opens up the certainty that
dominant religions will tend to treat others with less regard.
Separation of church & state benefits public schools by
allowing students & staff to keep religion from being
made known to all, & having it be a factor in participation.
Christians...
Atheist worker fired after refusing to attend company prayer meeting...
It reminds me of the default in US courts to swear to God
(the Judeo-Christian god) to tell the truth. To request a
secular oath is to notify judge & jury that one is not of
their faith, which is generally majority Christian.
This can have a prejudicial effect.
What do they care, eh. They're Christians, & not
defendants or plaintiffs anyway. It's someone else's problem.
