^I don't know enough about Autism. But there is a saying in Islam to make "70" excuses for your brother before concluding anything.
I think a lot of that wisdom applies here. We don't know what's going on in his life, if he is successful in life or not, and whether he has vested emotion into Atheist forums and people here too much not of malice but ignorance.
Anyways, may God guide him towards himself so he depends on him and doesn't depend on others, and seeks his pleasure and not the pleasure of others.
