Well, seems like your intentions have backfired, and by not putting in any effort, even if you were right, you ended up making my points look more valid. I do recommend people read and look into my sources, hopefully your advice to do so helps create more Socialists.
Yes, I know how the 2/3rds data was gathered, and I am aware of the other countries listed there. It doesn't invalidate my point, and the data is still sound.
On one final question, what do you mean by a rabbit hole of "starvation and misery?" Countries adopting Socialism got more food secure after doing so. Take the PRC, for example, which recently eliminated extreme poverty in a Socialist economy. If 15 million people per year are dying due to poverty, sounds like we need to move beyond Capitalism and into Socialism.
