Same Sex Marriage Vs. The Civil Rights Movement

I think that seeing the demand for recognition of same sex marriage as similar to the demands of the civil rights movement is erroneous at least because of these two substantial differences. First, with the civil rights movement it is very clear that the difference in color was not an essential factor allowing or disallowing the same rights or treatments to one group and not the other but was clearly superimposed on that process. The same thing clearly cannot be said about the issue of same sex marriage where the issue being contested , the difference in sex, is  a very essential part to the level that the process would need a redesign to fit the demanding entity.

Second, the civil rights movement demand was also a formula that showed the reasoning path to apply that demand. It was a simple general formula applicable to not only blacks but all colored people and people from all ethnicities and origins. The same thing clearly cannot be said about same sex marriage where the demand did not show how it should be applied and left the question of why it should be applied to one group and not the others unanswered. On what basis should recognizing same sex marriage of a man to man or a woman to woman and not a group of three or more of different - or even same later- sexes stands? Why should the number be taken as more essential to the marriage than the requirement of being from different sexes? I think that human history would provide indications contrary to such understanding.

Remember that as much as there are other paths that give the same marriage rights to same sex couples using different names as much as the question here is about applying the word "marriage" on same sex couples and not about the recognition of their marriage.
