Ridiculing is one thing. Waging holy war, murdering, burning and dehumanizing is unfortunately a common reaction to differing viewpoints among religious folk.
And I would add, the world is more peaceful and loving and moral under Christian morals (the morals we all currently share) than under the ethics of the Roman Empire. Christians ended the slave trade for specifically, uniquely Christian reasons. It was a religious issue. Modern progressives grew out of the Protestant culture of puritan founders. It’s why we embraced immigration.
It’s one thing to be ignorant of the creator (and deny creations miraculous nature), but to be ignorant of world history; please read about Rome.
