Without knowing specifically what the questions are that they were asked, it's impossible to tell whether this is relevant or the result of your usual right-wing persecution complex being fueled with a hackjob poll and repeated ad nauseam without any of the details (I've seen this sort of figure cited multiple times but never seen the original poll it supposedly came from) until everyone else believes it because it's been repeated so often.
Let's take the first one you listed- gays- and run with it.

Oh look, the media has a liberal bias! (We're not going to mention the fact that if you phrase the question like this the entire population would have a liberal bias.)
When it comes to something like this, always, always look at the original from the pollster; or else ignore it because there's no way anyone else can tell whether it's credible or not.
There are at least a half-dozen quotes in the bible saying that unbelievers should be killed, and a bunch more saying that people who perform certain actions (which aren't unethical from a secular perspective) should be killed. And of course, there's "be not yoked with unbelievers".
It's not a Quran-specific thing. All the Abrahamic religions have no respect whatsoever for those outside of the religion. The mentality boils down to nothing more than "hate everyone who's not one of us".
The explanation requiring the fewest assumptions is the most likely to be correct. -- William of Occam
