The issue, as i see it, is you criticized him for your own perception. Objectively, the picture isn’t about a father, brother, Uncle, etc… It’s just some person receiving what appears to be genuine affection from others. You taking it to the extreme of “it makes me feel bad because i think it’s implying i need kids for happiness” is the real issue. That implication is your subjective reality. OP isn’t responsible for that.

Given his target audience, that is the best type of ad.
