The point the fella is making is that he doubts very much there is any truth in the alleged peeping at a text on the train allegation. He has a point as well, anecdotal evidence such as this has been discounted as not reliable many times before if it does not fit the narrative, I have been a victim of it myself quoting one of my black friends and being being shot down In flames on this very thread during the upheaval after Floyd was murdered.
He’s not quoting whether it is a racist statement or not of course it is, He is making the point that it fits at the narrative of that we are terribly racist society that many like to adhere to, which on a whole we are not IMO
