Does the lost cause myth gave any historical backing to it?

by HistoricalFactsInc

I very rarely hear lost causers say something that actually have history backing it (like how they say the confederates didn't secede because of slavery) so does this myth have any actual facts behind it?

TL;DR - No.

The "Lost Cause" is a lot like saying I jumped from a sinking ship (no pun intended) because it was sinking, not because it hit an iceberg. The iceberg had nothing to do with me jumping. Sounds silly that way, right?
