Currently the abortion tag is defined as follows:
Abortion is a quasi-medical procedure in which a physician terminates a woman's pregnancy. It is a contentious political issue in many countries. Use this tag to discuss the politics surrounding the legality of the procedure.
The dictionary definitions I have found do not include the term "quasi-medical". This does not add anything to the meaning of the tag, but it does imply that abortion is not a legitimate practice.
The definition also excludes terminations carried out by non-physicians, which does not match the usual definition.
I suggest that the tag be redefined as:
The deliberate termination of a human pregnancy, killing the embryo or fetus. It is a contentious political issue in many countries. Use this tag to discuss the politics surrounding the legality of the procedure.
