A lot has been made of abortion, and it is worthy of a lot of attention, but do they advocate letting other sins or "sins" of a politician slide under the radar? What about politicians who want to be permissive on, not abortion per se, but sexual promiscuity? drugs? liquor? cigarettes? pornography? Etc.?
First off, let's try to put everything in proper perspective. The legalization of abortion, thirty some years ago, has caused the death of over 40 million human beings. Human beings that had no say in the activity that created them, no say in the decision to kill them and no say in the Supreme Court decision that made killing them legal.
Such activities as drugs, liquor and cigarettes, is usually engaged in by willing adults, and has over the history of humanity, never killed more humans than thirty years of legalized abortion has done.
Sexual prosmiscuity and pornography, while dehumanizing for all participants in many ways, is as a rule indulged in by willing adults. I don't endorse such activities, but feel it's none of my business unless children are involved in the pornography or children and uninvolved spouses suffer from the consequences of promiscuity.
In my opinion a politician should conduct him/herself in a manner that reflects the highest moral standards of those who elected them to office. Politicians should set the example, for others to live up to, and if they can't or won't, they should either be honorable enough to resign the office or be removed from office.
