In high school debate, I found a killer piece of evidence to counter any given doomsday argument.

From Eric Zencey:

There is seduction in apocalyptic thinking. If one lives in the Last Days, one’s actions, one’s very life, take on historical meaning and no small measure of poignance.

That's not evidence.

You just used a type of Ad hominem fallacy called appeal to motive fallacy.

Well, it was high school.

Not to mention it’s an assumed motive at that.

And yet many doomsdays have occurred.
