Parenting is one of the most emotional topics that exists, which means it's flammable material in internet discussions. If you lead by comparing parental leave to "hangover leave", that's already a provocation, and if you throw in more provocative words like "indulging" and "hobby", at that point you're posting flamebait. You're going to get flamewar responses, not a reasonable conversation, and that's against the site guidelines.

If you really want to have a reasonable conversation about a divisive, inflammatory topic, you need to sand off all such sharp edges. That's not a moral or ethical point, just an empirical observation about internet dynamics, which are relatively predictable.
