It's the lack of tolerance that causes atheists to want to remove nativity scenes from public places
Ahem, allow me to speak, as an atheist, because I don't think you have this figured out.
This is not about tolerance, for the atheists I know. This is about a principle. I don't mind if I see a nativity on private property. Some can be quite pretty. I don't get angry when I see them. I tolerate them quite well, thank you very much.
Yet there is a principle of separation of Church and State that is violated all the time. It is a constant struggle. Those of us that recognize that our government was meant to be secular, and those that tell an alternative history claiming that America is a Christian nation. (I'm obviously speaking as an Atheist AND an American--other countries may have different struggles). Why should the Pagan or the Atheist have to tolerate their town hall favoring one religion over the other? Is that not indicative of an overall attitude? My Wiccan friend lives in a city with a mayor that wants to adopt the slogan, Most Christian City In The Nation. Now why should she tolerate that? Does that make her angry when carolers knock on her door? Of course not.
It's not the place of government to be putting up religious symbols. It is not intolerance to demand they follow the Constitution. It has been reduced to that---oh-look at the petty atheists---getting all upset about a cross. It's not the cross that is upsetting. It is the principle that says a tolerant government is also a secular government. One should not influence the other.
So reduce it to the ridiculous if you like. But the issue is bigger and more complex. It is not the nativity scene that is offensive but the context. I am not offended by cuss words, however if I saw a pre-school teacher using them when addressing the children, I would take issue. Would that make me intolerant? I don't think so. Could it be reduced to me just being a priss that doesn't like bad language? Certainly. If that's the spin a person wants to give it.
