> Maybe I've come off the wrong way here. I do not believe that either party can claim the moral high ground for their decision on raising children.
And the difference is the OP literally was just talking about themselves and their own choices. Go read their comment. They even went out of their way to say "For me, it's practicing what I preach, because I view climate change as the most pressing existential threat to our species" and finished their comment by stating "If you disagree... more power to you! It's your decision to make, and I mean that earnestly."
Never once do they deign to make moral statements about anyone else. It's purely about their decision and why they've made it.
The only way to take offense to that is to look for it.
You, by contrast, proceeded to attack the person's beliefs, going so far as to say of their desire to have children: "you probably never really wanted them anyways."
As for this...
> For the record, I am 26
I'd wait until at least your 30s before you start telling people what they might or might not feel when they get older...
