Real leftists understand the principles of harm reduction. Voting for Harris, as voting for Biden would have done, has the outcome of reducing harm compared to trump winning. Sure, there will still be harm, but it'll be less, and that's incredibly important. It's basically the same foundation behind how we need to help drug addiction. Although Harris will likely cause even less harm than Biden.
Chances are that the "leftists" arguing for the purity test of Harris are people who aren't truly at risk in this election. They won't have their basic human rights torn apart if trump wins. They're leftists in name only.
Obviously, the Lord of the Rings Trilogy. Mainly movies for me because I haven't read them. Extended editions, obviously.
But also, I adore the mass effect trilogy. Yeah, the rpg elements get gradually watered down, and the third ones ending isn't the best, but it's still an absolutely amazing Trilogy that I replay yearly. And it all came out in 5 years! Nowadays, single games have 5 years of dev time, at least. In my eyes, it's as perfect as it can be....Once it's been modded a bit.
