All the Iranians I've met seem like completely normal people. I've never been to Iran, but from what I hear the young people in Iran aren't much different from the people here: They like to go to parties, listen to music, etc. The only difference is that they have to do it in hiding, and that they will get arrested when they do something like hold hands in public when they are not married.
Why would anyone approve of sanctions that make these people suffer even more?
And then, when these people start fleeing the country, asking for asylum, why do we turn them away?
