For people of his ilk anything that he disagrees with always is defined as the other's behavior choice. As a choice it can be assigned a negative moral value and ignored or discriminated against freely to benefit society.
The problem, as we know, is that no choice is involved. That is truth. But the opposition is not really interested in truth at all. I have seen it time and again on conservative forums where they are presented with facts and scientific studies and then simply dismiss it all without a thought as liberal conspiracies. That's what we are up against, a dishonest adversary, and there is no easy solution except to marginalized them by turning the bulk of public opinion around in our favor.
