If the opposite were true, the human race wouldn't have lasted this long. Most of us are the result of individual acts of human love.
Even though I agree somewhat with that. There are bacteria and viruses and other very "loveless" life forms which are much older then the human race and will most likely outlive us without the need for love,
Plus, if it truly was "human nature for love to win" we would live in Utopia and not in Reality land were people kill out of joy and greed. We'd just all love each other which is clearly not the case in the real world.
The progress you described is nothing new either. Many empires had more open minded views on sexuality and love then the modern western world. Look at India today and you'll see a bunch of sick shit on every corner. The same goes for China.
I'm not talking about non-human organisms right now, though some of them apply maybe. That utopia is where we're headed, but first we have to realize we're running around in circles and make the conscious decision to move forward. It's coming, but very likely not in our lifetimes.
Yes, we've celebrated weird sex at various times and places throughout human history. Until we stopped for whatever reasons we invented. This refers back to the running in circles thing.
Interracial love is nowhere "celebrated" let alone all over the world. Maybe in some hipster cities in the US and Europe but the rest of the world hates that shit.
I guess that's fair. But we've made tons of progress in the world I live in. Let's hope we make that progress last this time. If we don't it won't be a huge deal in the grand (grandest!) scheme of things, because we'll make it back there eventually. Love is always the eventuality.
That's just wishfull thinking on your part.
You think so? We're living in an exciting age of progress, and as we move forward fewer and fewer groups are holding tightly to the "gays = bad" view. Even the Mormons and Catholics are going forward, albeit slowly.
