Would you like to assign me any more imaginary opinions? Your reply is an exercise in whatabouttery: ignore this harm because look at all those harms over there. Controlling the age at which one has children is within one’s power to control, and helps to alleviate obvious harm. Nothing you have said or can say will change that.
Your statement that "the age at which one has children is within one’s power to control" is just obviously false. Especially for men. But also for everyone, if you're trying to time things to mitigate other disadvantages.
In reality, you may be 51, and may be in a good position otherwise to have a kid, and the question is whether being 51 is a reason not to. And the answer is "no", it is not. Not unless you also think that other people with non-major reasons not to have a kid shouldn't. In other words, not unless you think nobody should have kids.
