I don't begrudge anyone their beliefs or their personal desires and cultural preferences, certainly. But when they sacrifice their economic well being and their civil rights--or mine--in order to preserve or elimnate one 'right', that's just not very clear thinking.
So you think that it's unclear-thinking for someone to sacrifice their economic interests for some moral principle or to protect others?
They think abortion is the murder of unborn babies. They think it's as immoral and intolerable to allow that as it would be to legalize rape and homicide. Why is it objectively unclear thinking for them to prioritize that issue over greater economic prosperity?
Some of the most admirable and important acts come from sacrificing one's economic interest in order to pursue some non-economic principle. I don't agree at all that anyone who prioritizes that way is inherently irrational.
