People may CHOOSE to PERCEIVE it as discrimination against their favorite Beliefs.
But, do Christians feel bad that the NON-Christian Gods and Goddesses have Wotan's Day, Thor's Day, Freyja's Day, and Saturn's Day named after them?
As for perceiving any spoken words as insulting or discriminatory, it was a pagan philosopher who taught that it is not what OCCURS, but how we CHOOSE tro FEEL about it, which determines whether or not we are happy.
"Saturn" is the name of a pagan God which ate His own children. (Look it up!) Wotan, or Odin, is the chief Norse God, Freyja is his wife, and Thor is another.
