Let's say I was at a Democratic debate and wanted to make the liberals look like a bunch of idiots. So, hoping some would follow my lead, I "boo" something...
However, only me and two others are booing... Would you say the "audience" booed? Was it democrats because I was at a democratic debate?
Basically, when only four people "boo" something it isn't "the audience" when over 6000 are in attendance; and just because it was republicans on stage doesn't make it mean that everybody there were republicans.
And again, it underlines my basic premise. If they were "conservatives" (social "conservatives" are actually radicals who wish to change laws and basic freedoms to match their ideology, much like the radical liberals), it strongly supports my assertion that at most there are 20% social "conservatives" in the republican party.
