Here's a breakdown:

The parent is correct in that most muslims, broken down by country, do support sharia law when surveyed.
Edited because I was wrong about numbers.
Christianity has a lot more adherents (numbers wise) than Islam.

I'm a Muslim and this is the first time I hear that this is the "mainstream" position. Do you have any reasonable sources for that claim?
Multiply the percentages out and it does not paint a favourable picture of the actual interpretation of Islam, as believed by most users.
It's odd that you're downvoted. It'd appear that most of the people in those countries would agree with your statement exactly. They are devout, and that is literally what they believe.

... And more specifically:
https://en.m.wikipedia.org/wiki/Islam_and_blasphemy
Blasphemy is punishable in the vast majority of Islamic countries. Most Muslims worldwide support these laws, and most schools of Islamic jurisprudence support their position in Islamic law.
It's probably not true of most Muslims in Western countries however. I have a sneaking suspicion - but no way of proving it - that people who think this sort of thing is nuts are more likely to want to emigrate to countries without it.
Note that blasphemy is also punishable in many Western countries. This is driven by the same problem: religion. Usually Christianity.
It's important to note that a large portion of verses in the Quran were revealed to the Prophet in response to a particular event that took place during his lifetime. Tafsir (exegesis) is the subfield of Islamic science that deals with figuring out the context of a particular verse.

Also, the mainstream consensus changes over time - there has been a fairly long period, for example, during which the Sword Verse was interpreted to imply that the Caliph does have the authority (and in some madhabs, the obligation) to wage offensive war against unbelievers:

Had Al-Ghazali been less successful in his reactionary unwinding of the Islamic world's enlightenment, we'd probably be having a very different conversation now.
Also, it's a bit rich to compare a nonexistent flag burning ban (which would punish with fines or jail) to Pakistan's very-much-existent blasphemy laws (which execute people).

Some people get really uncomfortable when others don't fit into their tidy labels.
I also trust polls more than my own experience. If someone cites Pew saying 30% of Americans are young-earth creationists[1], I'd never consider responding with, "I'm an American and I know a lot of Americans and none of them believe that." I'd simply verify the data and accept it.

If these were American Scientologists torturing people for blasphemy and murdering people for leaving their cult, no-one would hesitate to point the finger at their religion as the problem.
