No, I have never lived in a socialist country, but I have visited a few of them... I have also done a fair bit of research on socialism...
Have you visited a socialist country, or done even the slightest bit of research into socialist policies?
Or, are you just saying it's evil because that's what you were told in elementary school?
Not evil of course. It's just not working. As I've (partly) grown up in a socialist country I can assure you that was an economic crash course from the beginning, and not because of the bad implementation but because of the faulty principles.
