GK I am not sure why you mentioned atheist so many times in your post while presenting a picture of a sick child molester, but you said you had no real knowledge of atheist being threatened or attacked by Christians. I can help you here. Watch this video and then you will not be able to make that claim again.
Also what did the attack in San Francisco have to do with atheist? I am just trying to understand why you have brought atheism into this discussion while posting examples of child molesters and angry homosexuals.
