I suspect the responses you’re getting stem from the original phrasing:

what’s the point, evolutionarily, to self destruct after reproducing

The question has an implicit claim that there IS a point, which people are rightly pointing out is not necessarily the case (as you have acknowledged). It certainly is an interesting question to wonder if there could be some benefit anyway, so it would probably have helped to frame it that way.

Not saying anyone is required to meet any kind of bar in the level of discourse in a casual online forum, just an observation of cause and effect, for what it’s worth.
