This is a very thoughtful and well argued comment and really informative.

I commend you for taking the time and effort to write this so well, despite the original comment being somewhat snarky and clearly opinionated.

I'm personally a pacifist and would like to end all wars, all weapons production, etc, but we currently do not have a way to enforce that over the whole world.

So the realistic view is that given that currently we have wars, need weapons, etc - it does make sense that YC would fund companies that develop new ones or new technologies in the space. Even if nobody really wants to hurt people.
