Atheists do not harass Christians unless your definition of "harass" is that they disagree with Christians and any other theists. Sometimes atheists get tired that Christians impose their religion on everyone - swearing on a Bible to tell the truth, praying before public meetings, praying for sick relatives, baptizing babies without the parents consent, being nice to religious leaders just because they are religious leaders - and speak up about this imposition of a superstition on their lives. This is hardly harassing.
