Who is to blame for the crucifixion of Christ?

It always bothers me when I see polls like this, or actually anytime that I see people trying to blame Jews for the crucifixion of Christ. It was the sin of men that led to the crucifixion of Christ. That means you and I are just as culpable as a Jew 2000 years ago. People should know this, and they should know that forgiveness of our sins and everlasting life are gifts to us through that crucifixion, as horrible as it was.
