I would think that evolution is absolutely anti-homosexual. From a natural perspective, a person being purely homosexual ends his line, period, do not pass go, do not collect $200. Homosexuality would be selected out. It's like the joke "Celibacy is hereditary."
We do have the rare aberrations in nature of homosexual activity, but mainly it's been found in humans who discard the natural order of things for their own pleasure and then try to get around evolution through artificial insemination.
"Global Warming" has a connection only in that we know the planet goes through warm and cold phases (whether humans are pumping out CO2 or not), and that affects evolution. Evolution doesn't have a connection with the True Believers who hate themselves and their species, and therefore want to blame us for everything.
And I also think we can all agree that the left has long used the theory of evolution in its attempts to destroy religion. Just like the US Constitution, religion and moral society must be destroyed in order for the leftists to succeed in their long term goal of ushering in a socialist Utopia.
And more recently, IMHO, homosexualism, feminism, abortionism, global warmingism, stem cell researchism, etc, have all been added along side evolutionism to the Marxist left's tool box of isms.
I say they're "Marxist" because the modern day Marxists, ie, the socialists and liberals, the ACLU, the Democrat Party itself, and the left-leaning main stream media all use these issues not as tools of genuine and sincere science, but as POLITICAL WEAPONS against us.
And I see it as a shame and disgrace that they have so many willing accomplices on the right aiding and abetting their subversive intentions.
