Right now I'm reading Libertas (I've read it twice so far) and realized I have to re-read Immortale Dei. But no, while some can't conceive of American Catholics being anything except Democrat others can't conceive of American Catholics being anything except Republican.
That's because Republicans (and Social Conservatives) revere abortion as being foremost. While other look at freedom and lack of restriction, as well as charity, as being first. Neither is right, neither is wrong. That's because both are right and both are wrong.
Republicans, while the hold anti-abortion as being foremost, because its the body of a soul, look on charity as being voluntary and would rather give of their own free will rather than be compelled to give. I understand this. For a while I did my employers charity campaign, which was cool. Until I started to want to give to charities who weren't on their "list". Likewise, Democrats view charity and tolerance of others as being more important while anti-abortion is a voluntary thing (but should not be imposed on other against their free will).
That's not to say that Democrat Catholics have abortions, just that anti-abortionism can't be imposed on the three-fourths of America who is not Catholic. Likewise, Republican Catholics engage in charity. They just engage in charity in direction that the law does not dictate.
You see, neither is right, neither is wrong. And both are right and both are wrong.
