Well, I don't know what he's getting at with the "kill" issue, but if the poster is gay, as an example, there are definately right wing nutjobs in the current (disfunctional, obstructionist, right-wing) republican party who would advocate that. Seriously. The republican party has been taken over by complete and total radical rightwingers. It scares the crap out of me.
Oh, another example that might fit with the "kill" comment. Their position on health care, abortion, contraception, and other women's issues, will mean more women dying. Examples? Planned Parenthood provides breast cancer screening, often to lower income persons who would otherwise not have access. Those women might DIE if they miss an early diagnosis because of such policies. I, for instance, was diagnosed as stage II with a mammogram.
There are a lot of (current) republican policies that are anti-life, in my opinion.
By the way, the old republican party, although I disagreed with them, at least cared about working with the president, regardless of party affiliation, to get things done. The current republican part is obstructionist, and cares for little other than undermining President Obama and getting elected. Although I tend to dislike all politics, the republican party has outstripped all their predecessors for dishonesty and, quite frankly, obstructionist evils.
