If you jump off an eighty foot cliff, the rocks at the bottom are not going to care what you claim to believe about gravity.
In the same way, if you say that a human child in the earliest moments and days of their physical existence are not human, not persons, they nonetheless remain human persons. And to intentionally kill them will still be murder.
And if you say that a man can marry a man, or a woman can marry a woman, such a thing will remain a moral and a physical impossibility.
No matter how powerful you think you are, you cannot redefine or change natural reality.
If you try, you're no different, really, than the man in the insane asylum who claims to be Napoleon.
Truly, you need to be restrained, to keep you from jumping off eighty foot cliffs.
