I agree it's good to care, and I think you're being downvoted because of your association fallacy. There are Christians that teach science, that believe in evolution, that aren't sexist, etc. There are also athiests that are sexist, are anti-vaccination, and homophobic. It would be just as wrong to say athiests have no moral standing.
If you want a future where people treat each other right, then don't demean them, else you're just continuing the cycle.
Atheism has no holy book nor organizations promoting such behavior, and there is nothing to indoctrinate anyone with. Christians behave like decent beings in spite of the Bible and the Church, mostly due to existing in a modern secular society that does not allow atrocities they did when they were in power. I fully recognize that there are many decent religious people, but that does not mean the religion is not promoting and causing said behavior in many many others. And I am specifically not demeaning the people as I see them as victims, but religion (as in the general concept, not just Christianity/Catholicism).
