I worry that we're sliding towards employer divide and conquer tropes here, being at odds with fellow employees over this makes no sense. Rather the onus should be on the employer to ensure they create an environment that is accommodating for all sorts of lifestyles. Why shouldn't you be able to take time off in a similar fashion to pursue your own child-free but otherwise time-consuming activities? That parents are able to WFH and work flexibly also confers YOU the rights to do the same. That is why I am personally extremely supportive of those rights despite not having children because it gives me the rationale to demand the same flexibility when I need/want it.
