Abortion is the destruction of a precious, innocent human life. It may be necessary when that life verges on causing the mother to die. But as a matter of elective options and rights, abortion is murder. The arguments for abortion are the same arguments used to justify and defend slavery. Abortion advocacy, in fact, derives from the progressive movement’s desire to stamp out black and disabled people in the early part of the twentieth century.
It is a quote from this article - No, You Cannot Support Abortion and Be Conservative/ - by Erick Erickson, who is one of the Conservative authors I quote frequently.
