re: I am a conservative, pro-choice and atheist. Is this weird?

Not really. Being a Christian isn't a pre-requisite to being a moral person who believes in the rule of law, free market economics, and the Constitution's limitations, separation, and division of powers between three branches and three levels of government.

As for the pro-choice side, I don't fault anyone for being pro-choice. While I find abortion abhorrent, I also recognize that it is one of the few issues where there truly are two sides of incredibly well-meaning people with absolutely valid moral and/or economic stances for why they believe what they believe on that issue. It is why I would find it shocking that liberals cannot respect others' views on that issue if I did not know the progressive playbook better than they do.
