the second component is the so-called "free exercise" clause, which requires that government be tolerant of religion and not adversely impact individuals for their religious practices, except where the practices impact on others.
and certainly abortion does not impact on others, how can the state regulate it on grounds other than a religous basis? it appears to be a religious argument that the "other" is a fetus. since the preponderance of fertilized eggs do not undergo implantation and division past the 4 cell stage, it can only be a religious argument as to when the "other" becomes into existance
