Growing up in the USSR they forced everyone to write with our right hand. You get beaten if you don't. Was really hard for my cousin because he's left handed. He just learned to fake it for the teachers.

Finally, a Ted Talk that didn't suck.

I agree that it's a form of torture, but someone can't ever have eyes be a different color because of the trauma. People do act like and belive they're straight because of the trauma forced upon them from conversation therapy.
They also often gain hatred of those who are like they "used to be", and there's no real mirror for that in eye color.
And just to be clear, I say none of this to minimise the horrors of conversation therapy.
