Science, Race, Homosexuality, Abortion, and Religion

This is long. Don't read it.

There is no genetic, DNA, or scientific basis for "Race." There is only the human race and everything else is a social or cultural construct. Yet, we revolve our entire lives and orchestrate public policy around the concept of "Race" with absolutely no scientific support for "Race" as anything other than something that we have come up with to rank or differentiate people for purposes of power. The science that tells us that we are all the same is ignored.

There is no genetic, DNA, or scientific basis for homosexual identities being something inborn. We go off of the testimony of gay people that they were born that way and they have no choice. Yet, there is no proof of that from science at all. The human genome has been mapped and there is no "gay" gene. There is homosexual behavior, obviously, but there is no proof of homosexual identity as in the idea that people are inherently born that way. We take the word of homosexuals on that as they assert their own identity. The result is that society is not completely altering itself to accommodate their assertion. Science has no bearing on any of this.

Science now tells us that a fetus/baby at 12 weeks is not a blob of tissue. It is a human being. At 20 weeks, it is developed at an astonishing rate. Babies can survive outside the womb at 24 weeks. Science is clear on this. Still, the only countries that allow for abortion after 20 weeks are China, North Korea, the United States, and Canada. In France, you cannot have an abortion after 12 weeks without a doctor's order that declares the mother's life to be in danger. Science is clear, but it has no affect on the debate.

Religion agrees with Science on Race (we all come from one man/woman), Homosexuality (we are not born that way, but we are all affected by beliefs, choices, and there are deviations in humanity), and Abortion (human life exists in the womb). Yet, Religion is considered to be irrelevant in these discussions even though Race is a social/cultural construct, Homosexuality as an inborn identity is only established off of the testimony/behavior of adherents, and Abortion is illogical apart from the desires of the mother. What makes any of these issues/positions more real or valid than someone with religious belief declaring that they have a view on an issue because of that belief?

I am not saying that religious belief should dominate society because a lot of people do not believe the claims of religion (and I am talking about religious belief in general, at this point). But, at the same time, why should society be altered by unscientific beliefs/desires in regard to Race, Homosexuality, and Abortion while at the same time ignoring the convictions of people of faith? What is the difference between the ways of approaching knowledge?

Just because someone has different physical features, how does that make them different? It is a social construct rooted in nothing more than the historical attitudes and fears of people.

Just because someone says that they are gay, why should we believe their testimony? It cannot be proven. Yes, they engage in behavior that is visible and they say they would not choose it and cannot change, but how is that not the same as religious belief where people die for their faith because they cannot NOT believe in God?

Just because someone says that it is their body and they can do with it what they want, including ending their pregnancy through abortion, how does that make it so? How is that scientifically true?

It seems like we hold the claims of religion to one standard while accepting spurious claims on other issues that are contradicted by science completely. And, we do not even bat an eye over it.
