The reality is that Atheists turned the 20th century into genocidal nightmare of unprecedented proportions. The fact that you had to go back 400 years for pathetic whataboutism is very, very telling.
You are looking into the abyss and it is staring back. Atheists are the new monsters. Take a look at what is happening in China, today.
While we all like to point fingers at our favorite boogie man, things are decidedly more complex.
Religion and State Failure: An Examination of the Extent and Magnitude of Religious Conflict from 1950 to 1996

Genocide is an ethnic conflict, and......

Results (p66)
"Another important aspect of the results is that
it is ethnic conflicts that are most likely to be religious. Overall, 47.6 percent of ethnic conflict years in the State Failure data set are religious conflicts as opposed to 25.5 percent and 19.5 percent, respectively, for mass killings and revolutions. This implies that the primary violent challenge that religion has posed to states has been in the form of conflicts between groups of different religions."

Conclusions (p70)
"In all, the evidence clearly shows that many conflicts continue to be religious. Since 1950 the number of both religious and nonreligious conflicts have increased, though religious conflicts have increased slightly less. Thus, while religion remains an important factor in conflict, it is clear that other factors, or at least
a combination of other factors, are also important. One factor that seems to have influenced the rise of nonreligious conflict is the Cold War. During the ColdWar, nonreligious conflicts became more common than religious conflicts for all conflict types, but after the Cold War all conflict dropped, with nonreligious conflicts dropping more than religious conflicts. If this trend continues, religious conflict will be about as common as other types of conflicts. In any case, it is clear that religious conflicts are still a significant percentage of all conflicts"
" ...
religious conflicts tend to be more intense than nonreligious
ones."
"
Religious conflicts are a minority of conflicts, both during and after the Cold War, while Huntington’s theory would have them the majority. Lastly, Huntington predicts that conflicts involving Islamic groups will be the most common, whereas
conflicts involving Christian groups are far more common.
As noted above there are many reasons humans will kill each other in addition to religion; real estate, money, and regime change notable among them.
Your attempt to paint atheists as genocidal maniacs is contrary to the facts.

I understand facts are not of much interest here but some readers may find them enlightening.
