I think you misunderstand. Ageism is about discriminating on the basis of someone’s age.

The original comment was about grandparents and parents neither of which you need to have a certain age to be one. Assuming that it IS about age is in turn actually ageist because you are signaling that people should be parents at a certain point in their life.

To be clear, I don’t think your intentions are wrong: you are just trying to right a perceived wrong. I am just asking you to grant others a more favourable interpretation of their intentions as well. I do this by pointing out that your well intended call out of ageism is in turn also interpretable as something unwoke.

Hence arms race. There is always someone who can be more politically correct.
