The same can be said about religious people. Crusaders were killing infidels and robbed their wealth
in the name of God. Conquistadors were killing infidels, raped their women, robbed their gold and conquered their earths
in the name of God. So let me use your own words: being a religious leaves them nothing to believe in, other than God, money and power, so there really is no difference.
So you failed to answer my questions? Ok, now I see you have no arguments to support your point of view. Don't worry however. This is a normal situation for any religion supporter.
Now about your questions (actually I don't have to answer them because you already gave up, but I'd do).
1) I don't know how many the "religious Buddhists killed". However Buddhism is more philosophy than a religion, because
THERE IS NO GOD IN BUDDHISM. Surprised? I bet you are

According to Buddhism there is no magic man in the sky who created humans, there is no God who tells them: "kill everybody who serves to other Gods" while Bible, Koran and most of other
creationist religions (<<< this is a very important part, so I marked it with red specially for you) says this very straight. E.g.:
2) I'm already explained you why this question is wrong. They don't kill people just because those are religious but they are not. They kill people that interfere with their regime. It's the same if you ask: "how many people were killed by redhead guys?", "how many people were killed by guys with a mole on the left shoulder?", "how many people were killed by guys with mustaches?" etc. That has no relation to religion. So all these questions (including your one about Chinese) are nonsense.
You have nothing to say on topic thus you are just trying to repeat the same misleading thing like "how many people were killed by guys who speak English?" This won't work. At least with me.
