They are atheists who are using Satan (who they also don’t believe in) to antagonize Christians to the point that they will give up on displays of religion on public property. It seems be working.
Bingo.
That “display” was something a grade schooler would put together to be funny or shock someone. It was completely stupid.
If someone wants to display that on their own property or space they have personally paid for...I have no problem with it.
What the heck is garbage like that doing on state property with the blessing of the state government?
I think your post is the root of it with the state government willing accomplices.
