Im aware of that. It doesn't change the fact they want the legal right to discriminate.
If you're aware of that then you will have to acknowledge that it is your ideological position instigating the view that it is "discrimination" and not theirs. Your position doesn't agree with theirs, neither does their position agree with yours. Your conclusion here is just affirmation of your own position, nothing more. It is hypocrisy.
They tend to have thousands of years of thought and philosophy to guide them, and generally adhere to humanism. Christians have what passed for morality and ethics during the bronze age.
But you know that your statement here is completely intellectually dishonest, to the point of intentional ignorance. Christianity didn't end at the Bible, nor did Judaism, Christianity has 2,000 years of intellectuals, philosophers, scientists etc. If anything it's the other way around and Humanism is a cherry-picking anti-religious ideology that takes the bits it likes from Christianity.
A case could be made, if you want to poke into that hole, that your modern morality is ancient archaic barbarism reinvented for the 20th/21st century. Two can play at that game.
Its Christians who cry foul when they are reminded they have to share this society with other people and that they dont get to run the show.
I simply do not see this happening myself, only Atheists crying wolf again and again because they oppose religion(s).
They do so much whining and crying they think "xmas" is an attempt to remove Christ from Christmas even though the X still means Christ, and they insist there is a war on Christmas even though we still very much say merry Christmas and even Thanksgiving has been taken over by Christmas.
I have nothing to say on Christmas, Santa Claus is not in the Bible far as I'm aware.
