When changes that should have taken a thousand more years happens in just a few years, I become very very upset.
I find this very interesting, are you saying that you think same-sex marriage should only come about after thousands more years? You are right, I suppose, in saying that the past 100 years or so have seen dramatic social change, what with the sexual revolution of the 60s, suffragettes securing women the vote, etc. And of course, Hitler made the far-right fairly unpopular, which I'm sure has a lot to do with why society veered into very liberal zones for the rest of the 20th century.
Is this the kind of thing you're talking about? Vast social change in a very short time. I'm not an absolute expert in all areas of history, but I'm quite sure that if you picked two years, let's say for arguments sake 1515 and 1615, you would see less social change between them than that which occurred between 1915 and 2015.
I for one am happy with the direction we're heading in as a society - though I can absolutely understand why some people may find some of the more radical aspects, such as the growing awareness of transgender issues, quite hard to swallow. I'm sure that for every person genuinely suffering from these problems, there's another who is just crying "oppression" for attention.
It's important to remember, though, that we can't assume our views are correct just because we're born into them. In Ancient Greece and Rome, they believed a prepubescent boy was the pinnacle of beauty, and it was common practice for fully adult men to start erotic relationships with boys of about 12, in fact this was more common then two adult men having a relationship. This seems wrong to us now, but at the time, no one would have batted an eyelid, because they were born into this value system.
