A description of Secularism:

"In political terms, secularism is a movement towards the separation of religion and government (often termed the separation of church and state). This can refer to reducing ties between a government and a state religion, replacing laws based on scripture (such as the Torah and Sharia law) with civil laws, and ELIMINATING DISCRIMINATION ON THE BASIS OF RELIGION. This is said to add to democracy by PROTECTING THE RIGHTS OF RELIGIOUS MINORITIES."

The alternative is what?
Your view that this promotes racism maybe so in the American model but I struggle to see haw this can be the case in the EU.

"Deaths in the Bible. God - 2,270,365
not including the victims of Noah's flood, Sodom and Gomorrah, or the
many plagues, famines, fiery serpents, etc because no specific numbers
were given. Satan - 10."
