Your premise seems to start from the point that you know exactly what a human being is, or what life is in and of itself. You seem to have no doubt about the ability to create, shape, influence human life through genetics to ensure the continuation of the human species, yet doubt is the very basis in science.

As you are unable to define exactly what a human being is and what life is, I would take your statements for what they seem to me to be: the expression of exaggerated fear and resistance to one's own certain death.

I interpret your lines as a form of self-loathing, dressed in great eloquence and intelligence. I attribute this to a form of one's own experienced past, in which sexual permissiveness was suppressed by someone in one's environment. The church and all its extensions, which were eventually also grounded in science, still seem to be a very strong influencing factor based on the guilt and original sin attributed to man.
Presumably no scientist holding a well-paid job as such would even remotely admit that his own cultural background gives him various blind spots that contradict his "objective science".

You are much less likely to distance yourself from those who you say would meet you with sudden silence or you would have broken a taboo. The signs of the times rather indicate that this topic will soon no longer be taboo either. Perhaps you are just not included in the circle of those who speak the same language as you.

I interpret that you have a very negative image of human beings and speculate that your personal experiences promoted this bad image of human beings instead of relativising it.

I don't worry in the least whether "our genetic material is giving us an increase in people who are unfit to live". Your text wants me to see it otherwise and share the worries.

We have seen such allegedly altruistic behaviour of "putting the ego beneath the good of the many" in the last years, haven't we?

In fact, I fear such arguments and claims as yours more than what you seem to fear. This puts our two fears in competition and the desire for one to dominate or win over the other seems to me to be the real problem.

Where culture becomes a cult ("Save the planet, save humanity!") I see madness, while you may see reason.

Which announces a struggle and where majorities turn against minorities without really knowing who is the minority or majority. The talk of a minority taking advantage of the majority, and vice versa, obscures the fact that unity "across the planet" cannot be achieved and only the controlling attempt to achieve it leads to further problems. In order to make unity attractive, you have to use the picture that "a threat of unimaginable consequences is hovering over humanity, yet man doesn't see it."

humans are nothing but bundles of unhealthy wishes.

You seem to know what humans are. I argue that you know not.

For me, humans are in the same way fabulous and impressive as they can be egocentric and mad.

Instead of taking this circuitous and justifiably controversial path of influence right at the beginning of human life, I suggest that you take a closer look at the freedom to express yourself musically, artistically and in dance. A much easier way to counter your feared degeneration of humanity. Instead of wallowing in the horror that could still await "us".

Enjoy.
