Allow me to clarify;
I agree that pro-abortion and pro-abortion and pro-gay marriage(for example)are contrary to Biblical teachings.
Therefore a Christian SHOULD not support these things.
But a Christian CAN support them and simply be wrong on these issues.
All the warnings in the New Testament to Christians against sin and false teachings tell us that REAL Christians are capable of self-deceit and sin.
Secondly I would disagree with you that all political liberal positions are opposed to Biblical teachings and vice-versa for conservative positions. That is far too simplistic a view.
We'll disagree
I would say that a person claiming to be a Christain but supports those or any other type of those issues needs to seek Fathers heart.
And I'll leave it at that
God Bless
