Let's see. An international busybody comes to your country to tell you how to run your elections. I think I'd get angry too. Especially since he's not just a plain old busybody, but a billionare busybody global socialist who wants to see global socialism before he dies (and he's 80 so he doesn't have a lot of time). Yep, I can see why people reacted.
Soros is pro-abortion, pro-euthanasia, and pro-socialist, and one could surmise strongly anti-Christian. He put millions into supporting training of med students in this country to help them get over their vision of a sanctity of life. Now his former students are promoting the idea of organ removal from still-alive, but brain-damaged and chronically ill children in the ICU in Boston. Young fresh organs, why wait for those kids to die, anyway?
He is the very epitome of evil in every direction you look.
