Can someone tell me what happened here? In this conversation I had with someone online?

Basically the convo went like this

Me: " yeah i was told i have aspergers "

Guy: " aspergers doesnt exist "

Me: " some people still diagnose it, thats what I was told i have from my doctor "

Guy: " you mean your from a 3rd world country? makes sense you type like your in a third world country "
