Poor analogy. Force implies no choice. Now, you could vote for someone who favors right to die legislation and still be a”good” person if someone then chooses to exercise that choice.
Abortion has no choice for the baby. Making private citizens take part in gay weddings is not a choice. Putting your name to policies which God calls evil is akin to denying the power of the Holy Spirit. Can you call yourself a conservative if you vote for someone who supports confiscation of property and redistribution of wealth?
