Number 2 doesn't excuse this shit, there are people who've been in far worse positions than having an autistic kid, ask them if they chose to do what the f**k they wanted or if they avoided attending hospitals, care homes, crematoria or grave sides.
Don't go losing your perspective because the word autism arose, this arsehole has access to help that mere mortals can only dream about, he wouldn't be waiting 3 weeks for his home delivery or similar.
