It's so disheartening to see that, despite all of humanity's technological & informational advancement, there is still so much primitive hate & fear for other people. There is currently a serious backlash against LGBTQ+ lifestyles in the U.S. and other places. Although I'm a straight white dude, I think other people should be free to pursue whatever experiences make them feel good. However, I also think that there needs to be limits - such as intentionally causing harm to others, or subjecting your will to non-consenting parties. Having a son now, my wife & I often discuss how we're going to deal with the complex issues of sexuality / identity. I don't think it's appropriate to force these ideas on young kids, but you also can't shelter them forever. Although what should be displayed in public is very subjective, especially when children are involved, common courtesy & discretion are ideas that I think are generally beneficial.
Sexuality and gender is such a contentious subject because it is such a basic & important aspect of being human. Sex = survival of our species. However, we have gone beyond biology in many ways - allowing us to experiment & experience possibilities outside the evolutionary imperative. So, I don't think the importance of biological purpose is enough of a reason to restrict anyone's sexual preference & other forms of personal experience.
I feel bad for people who are still offended by alternative orientations, such as homosexual or transexual. Guess what??? Things are going to get waaaay more interesting... with the explosion of A.I., as well as advancements in both physical & mental cybernetic augmentation, and bio-hacking the body to create "un-natural" biological systems. What we understand to be "human" is going to continue to evolve & change. Fear and resistance will not stop the change, any more than it stopped the transition into the Information Age.
Besides the morphological changes humans will undergo due to technological advancements, it is also inevitable that people will be straight-up fucking robots or virtual entities. So, people who are currently disgusted by people's "unnatural" sexual preferences for other human beings will absolutely lose their minds when they see the techno-debauchery to come!
There are many things about emerging technologies, especially artificial intelligence, that freak me out. However, I also know that things will always be changing... so you have to be open, ride the wave, & realize that the future is coming, despite your fears and feelings.
