Inspired by the WW2 cliches thread, what are some cliches about TLs involving the ACW that you find particularly annoying? One of the ones that bugs me the most is that in every single Confederate Victory TL, there is always a surviving Mexican Empire. What in God's name is the reasoning for this? Forgive me if I'm wrong, but the Confederates didn't give a damn about Maximilian AFAIK. Hell, they could easily supply the Republicans as much as the US did OTL. Not sure why every scenario has them propping up a corrupt, weak, and unpopular government as their closest ally geographically speaking.
Another cliche I hate about ACW timelines are the massive Confederate land-grabs. Doesn't strike me as the kind of thing they'd ever be likely to do. The even worse cliche, and God knows how it actually became common, whenever Texas becomes independent in a Confederate-Victory TL (which would probably be 90% of them) they make HUGE goddamn Mexican-landgrabs ON THEIR OWN! IIRC OTL Texas was pretty damn weak before joining the Union. What about Texas makes it stronger on its own?
