When most relationships are hetero, just calling out hetero pairing as a proxy is.. perfectly fair. That's not some kind of secret exclusionary dogwhistle just to use common language.
If parents are almost always a man and a woman and you say "kids with a mom and a dad"... you're just using the English language.
Dogpiling someone and attempting to shame them for "a lack of inclusivity" isn't some kind of meaningful attack, it's just a failure to be a useful communicator.
Anyway, I'm not the one failing to communicate usefully here. Did you actually read the original comment? It has no meaningful content. It is just a more verbose way of saying less than the title of the article -- unless you read it literally, in which case it's an explicitly homophobic way of restating the title.
I'm not aware of any ways to create a child without that.
Call them a "sperm maker" and an "egg haver" if it makes you feel better but that's reality.
Encouraging both of those people to take on the role of mother and father and parent together isn't some crazy, outlandish idea.
