You don't have to agree with the right on this issues (I don't on most of them) to think that saying it's just motivated by cheap authoritarianism and hatred of out groups is a slur. Sometimes, maybe, but not always. Perhaps on certain issues, like the ones you mentioned, gay marriage and immigration, it's even a majority. But even there it's never always. In fact, as I've suggested you could use the same slur against the left and it would be just as much of a half-truth. Questions of liberty are invariably questions of balancing one groups freedoms against anothers, for both left and right, and I don't think it serves any purpose to pretend that there is, or at least is most of the time, a gaping chasm between the two camps in terms of motivations.
So you rightly disagree with the broad brush premise of this poll, then you pick out my broad brush response written to reflect other broad brush responses as an example of ruining serious debate? The poll is in response to the political matrix poll, which was itself measuring people on a political gradient in response to the big issues of US politics some ten years ago, of which on most social issues even the most stubborn Americans have shifted at least marginally 'leftwards' on those issues. Sunday trading (of which as a union rep I believe should be curtailed) doesn't get much of a look in. I'll rememeber to give long winded answers to pointless poll questions in future
