A high school pre-AP Biology teacher in Kentucky has been accused of promoting Christianity in the classroom, and you don’t have to take my word for it, because there’s video evidence.
Where there are apparently multiple instances of this happening, one particular incident was caught on tape. It began when the teacher showed this wordless one-minute video of the M51 Whirlpool Galaxy in which, from a distance, it appears as if there’s a cross at the center of it. (It’s nothing of the sort.)
