Just because you didn’t experience / notice the issue it does not follow that ...

- It "wasn't a problem in your day" aka "the youth of today" argument

- it wasn't happening /despite/ your obliviousness

- you have any right to disregard/diminish/dismiss other peoples lived experiences because they don't match your narrative

- you are in any way excused from trying to pull your weight in addressing the issue now that you /are/ aware of it.
