I agree with Dathi, I read LTTW far more than I look at the rest of AH.com combined. I really should check the site and other timelines more...
If you want my recommendations for other TLs I read, at the moment it would consist primarily of:
Anything by EdT (currently "The Bloody Man")
Fear, Loathing and Gumbo by Drew
That Wacky Redhead by Brainbin
All Along the Watchtower by 03771
The Prodigal Sons Return by Dan McCollum
The Dead Skunk by Lycaon Pictis (I would particularly recommend that one if you enjoy LTTW)
Arose From Out The Azure Main by Iainbhx (ASB, an ISOT story)
I actually have no problem with radically progressive racial attitudes being bandied about. This world is already in reaction against the racist extremes of les Nazis, after all.
Again I wouldn't call them necessarily that progressive...if you time travelled to 1776 with Barack Obama and introduced him to the Founding Fathers as 'an Ethiopian prince' or something, they'd probably have no problem with treating him as an intelligent human being. While prejudice has obviously always existed, the particularly vicious "scientific" racism of the mid-19th century was not something that had always existed and was just coming to the fore now, it was something that came with the way societies were developing at the time (chattel slavery coupled to industrialisation in the Americas, colonialism in the UK and Europe, etc.) Context is very important here.
