It is at least an improvement from Christians that they haven't (yet) resorted to vandalism for these ads. Nice to see that Humanist values of free speech and respect for those you disagree with are starting to be accepted even among some religious people.

"kind of weird statement." Atheists have made their messages as innocuous as possible, because the religious view almost anything more assertive than this as "strident", "militaristic", "controversial", etc. This is due to the taboo against the criticism of religion which all religious authrorities promote (out of self-interest).

"As an unbeliever you speak the language of your father" That's a bizarre claim, given that a quick glance at a map indicates that the vast majority of the world's humans have religious views which are identical to their parents. I wonder why that is?

Defacing the ads with vandalism would be more in keeping with Christian ethics, so it's nice to see these Christian critics have adopted a more civilised approach, and merely stalked the atheist ads, like a creepy pedophile priest. On second thought, maybe stalking is more in keeping with Christian ethics . . .

"Let these atheists do this during Ramadan or Rosh Hashanah or Diwali" Why? The point is to reach the majority of the population. Therefore doing this during Christmas makes the most sense. "It's cowardly and hypocritical" No, it's effective planning. But thank you for demonstrating that your response to this issue is one of defensive Ad Hominem attacks.
