I suppose I should have written "good ideas." They don't die because people recognize they are good, and there will always be at least a minority that will keep promoting the idea.
You could enslave most of the people on the planet, and a minority will still press for liberty. They may not be successful and pay a heavy price for it, but they will continue to hope and fight for it.
Do you believe most people are bad/evil? I do not. I believe most people are peaceful, and they have no problem with consent and voluntary interaction.
I believe most people try to survive and they are just caught up in situations where the losers call the others "Evil"
Yeah, I don't believe in "evil people." There are evil actions or evil lack of action. It's something that is done or not done. Some people think guns are evil for example. Nope!
