1980s is the clear answer.
How can any progressive like the 1980s? They represent the triumph of everything wrong and bad.
The 1980s is when people tried to achieve all the
popular ideals of the 1960s/70s:
'I do whatever I want, whenever I want, I'm a totally free person, I want to fully realize myself, woohoo!!'
Something like that, through capitalism (something in which we still desperately are, and feeling it turns bad, we now try to go back to our fantastically fantisized traditions, and back and forth and back and forth and...).
All the actually anti-capitalist/anti-imperialist stuff was only the boring part of the story to excite a bunch of students...
There is nothing 'awful' about that...
As to answer the original question, heck, wasn't I born in 1983? Then you got the answer!
Well, I tend to be more attracted by the XIXth century anyhow. XXth might have been the fastest one but maybe one of the most awful one too.
XXIst seems to be so full of so many huge challenges that at the very least it might not be uninterresting...
