How can the use of the amendment process described in the constitution be described as not conserving the constitution?
Was it not conservative to amend the Constitution so that black folks were no longer a fraction of white folks? I'm not getting where you are coming from.
At the time, no it wasn't. Politically, "conservative" generally means opposed to or approaching change with some degree of trepidation. As it stands, questions of marriage and abortion are (or if the 10th Amendment were held to, would be) the pervue of the States. This is a tacit assertion that the States should not be trusted with those decisions.
