"Typical" and "normal" are synonyms to all except those seeking a reason to be offended.
I wasn't particularly offended by the original comment. Am vacillating a little between offended and amused by yours.
There are several autistic people in my life that I love and have watched have very real, not just semantic battles with what is considered normal. Both inward and outward struggles.
I fail to see how these battles make "typical" and "normal" not synonymous.
