Easy fix, just don't talk about what you know to random people. :)
It's like trying to sell icecream to people who hate icecream. Also, I certainly didnt learn about these things from someones comment on the internet. It was just watching world events like 9/11 and not being a complete moron believing the official story. :)
Then I got interested, found lots of good documentaries. YouTube used to be full of very good ones before they deleted them. I was very interested in that stuff.
Now the world is very different and people are seeing evil openly in the white house even. But it was very different back then.
You wouldn't evolve if there was no evil. No difficulties, no hardships, no madness. People acting logical and sane around you. Easy mode.
Now you evolve through pain and suffering. But its temporary. We are not here that long.
If God exists, he created this experience the way it is. So just accept it and try to manage it.
