Earlier quoted context omitted.
It's becoming more and more common for single men to adopt children. But yeah, expect some scrutiny. Otherwise we failed as a society.
HN is a global forum spanning multiple countries and even more societal mores. To your point though, "we" already failed as a society by not sufficienty scrutinising the bulk of adoptions to ostensibly stable 'ideal' families in decades past. A number of these adoptions turned out fine, many did not.
That is correct, and what is trying to be corrected for now.
