Opposition to abortion and Roe v Wade is not a Conservative position.

It is my understanding that the principles of American conservative political philosophy are:

• Protect & Maximize Individual Rights

• Ensure a Limited Government

• Uphold the Rule of Law

• Commitment to Federalism and the Separation of Powers

• Maintain Free & Open Markets (Economic & Social)

These principles certainly prevent the opposition to abortion and Roe v Wade.  As indicated above, true conservatism calls for prioritizing the rights of the individual and minimum involvement by the government in the personal life of the citizen. 

Opposition to abortion is based solely in religious belief. Contrary to conservative principles, the so-called “evangelicals” of the religious right want the government to tell people how to live their lives.  The specific religious beliefs of one sect or group must never be legislated. The separation of Church and State is a cornerstone of American democracy.

If your religious beliefs tell you that abortion is wrong –

+ Don’t have an abortion.

+ Work with groups that educate the public on methods of contraception.

+ Work with groups that provide health, counseling and adoption services for pregnant women.

But you CAN’T force a “non-believer” to follow your religious beliefs.

And you CAN’T legislate the specific religious beliefs of your individual sect or church.

Donald T Rump is most certainly NOT a conservative and most certainly NOT a Christian.  His current opposition to abortion is a convenience - Trump once again pandering to his core cult of ignorant racists and the religious right.  In 1999 Trump said he was "very pro-choice" -
