What a shame. My thought is that religion should be kept out of public schools. Certain things are passible because they are flexable. If you cringe at the WORD God., replace it . Christmas or other holidays that are typically celebrated in school are typically generic.
Private schools are another matter.
At young ages , difference become too big and overshadow any educational progress that they should be making. In this of all countries that should be understood. But all of this can be done silently and without bothering others. I don't buy the 'disruptive clothing' idea. People should be allowed to write, think, dress, learn, and manipulate energies in any way they choose AS LONG AS they do not violate the rights of others to do the very same.
