I'm just not sure what your claims about regime's repressivenes are based on. Were you there? Can you compare that with your current existence?

Exactly! It wasn't much better or worse than your garden variety society. That you won't use all the repressive words against.

Isn't that exactly the action of post-Perestroika, now-democratic Bulgaria? Indeed, as I have heard most of ethnic cleansings happen in young democracies as opposed to autoritarian states. In young unstable democracy, it suddently seems like a good idea for 70% to get rid of a 30% minority (numbers may vary). After all, you can vote solidly in favor of that.
If Socialist Bulgaria wanted to get rid of muslims it would not wait until 1989. They had 40 years to do that if they wanted. They didn't. The new, emancipated one did.
