So your response is to excuse them as insignificant because they didn't rape, rob, torture, and murder as many people as non-religious zealots did? (Because Christian religious zealots must always be excused of wrongdoing.)
When was the last time Christians did those things?
I am seeing this as being a common reaction, here. Deflection by blaming someone else of something worse. As if that somehow mitigates the original observed wrongs.
No one has dismissed anything.
Here is the problem.
Zealot "X" decides for himself, by reading tea leaves (let's say), that God is speaking to him through the leaves. And, he automatically presumes that his interpretation of those tea leaves is an accurate understanding of the divine messages that he's receiving. The result being that he has convinced himself that his concept of, and interpretation of those tea leaves are coming directly from God. And therefor they cannot possibly be wrong because God cannot possibly be wrong.
You see what he did, here?
Armed, now, with this presumed special God-knowledge, Zealot "X" sees himself as a God authorized messenger to the world. And when anyone in the world dares to suggest to him that he is not a God's authorized messenger to the world, he perceives them as being 'anti-God', and thereby deserving of forced correction, punishment, condemnation, and whatever. Because Zealot "X" has deemed his own beliefs about God to actually BE GOD. He thinks his own beliefs about God have become infallible. Unquestionable. Undoubtable. And anything that Zealot "X" does to anyone else that's motivated by those unquestionable, undoubtable beliefs must then also be infallibly righteous. Zealot "X" no longer has a conscience. He has overridden it with his self-assumed divine righteousness. And he is now capable of burning witches, torturing homosexuals, enslaving "non-believers" and doing whatever he thinks his divinely righteous interpretation of the tea leaves tells him to do.
This is why religious zealots are particularly dangerous to humanity. It's because they turn their own beliefs into their God. Rendering them unquestionable, undoubtable, and anything they do as a result, they presume to be infallibly righteous.
Christians != Zealot "X"
The Bible != Tea leaves
God does not speak to people directly currently. The last time it happened was with the Apostle John, around AD 90, to give him the Revelation of the end times.
Yet God can still speak to humans through His word, the Bible, simply by the people reading the words on the page. It's not a supernatural occurrence. It's just people reading what God has said.
