The florist's refusal is seen as discrimination.Yet the fact of her personal faith and doctrine are being discriminated against by being compromised by the homosexuals and their supporters and the injustice of the courts application of one sided legal action.
Also from a Biblical perspective the courts and the homosexual supporters, ACLU etc, are sanctioning sin which sends people to hell.
Thus in doing so these "atheists?"/"secularists" are discriminating against Christians their beliefs and their rights to declare Bible facts warning others about sin and God's punishments, - on the basis of "atheist" beliefs.
May God have mercy on all involved.
