A bit of a weird question: Can modern medicine be a threat to humanity long-term by greatly reducing effects of natural selection? (lemmy.sdf.org)

OK, I hope my question doesn't get misunderstood, I can see how that could happen.
Just a product of overthinking.

Idea is that we can live fairly easily even with some diseases/disorders which could be-life threatening. Many of these are hereditary.
Since modern medicine increases our survival capabilities, the "weaker" individuals can also survive and have offsprings that could potentially inherit these weaknesses, and as this continues it could perhaps leave nearly all people suffering from such conditions further into future.

Does that sound like a realistic scenario? (Assuming we don't destroy ourselves along with the environment first...)

OG Luci is right, though. There are far more people due to modern medicine. So if we suddenly lose it, there will be a lot of death. But there is more population and diversity to draw from the survivors. So I don't think it's a threat to the species.

Exactly, even if 7 billion people died, well there's still a billion people. If 99% of people died, well there are still millions.
