So is there a reason people don't post hot-takes about Muhammad and the Quran?

Here's some. Stick with it: https://www.youtube.com/watch?v=wOb2KQHr7V0

It's because he doesn't have a funny picture on here like the Jesus one...

It's hardly a mystery. It's because most of the people you're hearing from are from countries that are predominantly Christian. The people they know are predominantly Christian. They grew up hearing mostly about Christianity. The media they've consumed all of their life, when it had to do with religion, mostly had to do with Christianity. So, of course, Christianity is going to be the thing they speak mostly about. Because it's the thing they're most familiar with and what they've felt, personally, effect them the most. They're ignorant about Islam just as they're ignorant of most other religions. Heck, most who criticize Christianity don't even know much more about it than the unavoidable stuff (Noah's Ark, the resurrection, Adam and Eve, etc) that anyone in a country such as America, for instance, can't help but having heard about. But they attack it because that's an enemy they regularly see, hear from, and know about.

Half of them appear to think Islam is a race. They hardly know anything about that religion other than the fact that some terrorists had it and that people on TV warned us about remaining careful about accusing every Muslim as being like them. Most have no idea about how many "extremists" there actually are or how bad things are in other countries. When they hear words like "extremist" their minds instantly go to their idea of Christian extremists and they assume it's just a tiny, crazy fringe ("every group has them!" they say) who carry the really bad beliefs. But, again, even for those "really bad beliefs" most are completely ignorant as to what those even are, aside from them having some connection with the occasional terrorism.

It's because Christians don't chop people's heads off for blasphemy. Most anti-Christian bullies are cowards and like victims that don't fight back.

1. It sounds like you want to go back to the good old days when believers could stone the blasphemers.

2. In the West criticising religion hasn't been controversial for a long time. Irritating for believers but not controversial.

3. I don't criticise Islam because it's only a minor religion in my country and I know very little about it. Christianity however is in my bones.

4. I suppose people poke fun at Christianity because it is a house of cards as a religion and as an institution. And historically the Church has been unmasked for not living up to what it preaches. Nobody likes a hypocrite especially one that occupies the high ground.

5. Christianity has a huge problem. For anyone capable of looking at it as a historical phenomenon and not a religious one then its claim to be the one true religion falls very flat. But at the same time Christianity has undoubtedly done much more good than harm. The success of Western Civilisation with Christianity as one of its foundation stones is testament to that. So how to preserve the cultural legacy of Christianity in the West while the religious side diminishes ? That is the difficulty.

I think the main reason is fairly obvious-- this site is mostly used by people in the U.S. and other countries where Christianity is the main religion. People are going to poke fun at what they know, and what they most often see. Muslims are a relative rarity in the U.S. The internet tells me they make up only 1% of the population, as opposed to 65% of the U.S. being Christian.

The simple answer is that people are cowards. They know mocking Jesus is fair game but mocking Islam will result in real-world repercussions like cancellation ( for political incorrectness) and death threats. David Wood on youtube has countless videos about it, you should check him out if the subject interests you.
