This is such a vague question that you're not going to get a straight answer.

For starters, you need to quantify "right." Some might argue that woman's rights, religious freedom, and social liberalism are all bad things and that we've gone down the tubes over it. There's literally a subreddit devoted to people who are monarchists (http://www.reddit.com/r/monarchism/) and would point out quite readily that France losing it's crown was an awful idea. There are still people today with genetic ties to the old Royal Family in France who claim they have a legal right to reclaim their throne.

Similarly they might point out just how liberal and decadent the Roman empire had become when it began it's decline.

It's 100% perspective. If you honestly think any broader philosophy is silly and inherently wrong headed, you need to stop, turn off the TV, stop reading blogs and webpages that are profit minded (ergo, they're designed to elicit clicks), and actually sit on it. No one woke up one day and said, "damn, I can't wait to beat up some non-white people." or "I can't wait to deny my wife the right to vote." or "I can't wait to have my abortion" or "I can't wait to beat up some dirty hippies."

Sound bite politics are toxic, and operate at the level of the inverse meta. It wants to draw a narrative where you can only ever hope to understand one side of a story, and that pluralism- the idea that more than one thing can be "right"- is heresy.

Sorry, we don't allow throughout-history questions. This is also a bit of a politically charged question, which we don't allow either. You may want to try /r/ask_politics.
