Well, journalist John Nolte has been investigating the matter. After all, if Barry is still out there, he's likely to rape again. If Barry is not out there, then a man named Barry who used to go to the school and is now being regarded with suspicion will be exonerated.
Turns out that there's just no evidence that Barry--as described by Dunham--exists (if we can trust Nolte which seems plausible). Read the whole thing, but in case you don't, I'll provide below what I take to be an excellent example of the left's disregard for truth in favor or their narrative. What follows is truly amazing (but not at all surprising).
Setup: Nolte wants to go to the radio station on campus, since "Barry" allegedly hosted a show called Real Talk with Jimbo (according to Dunham's book). He asks to check the archive to search for any evidence that there was such a show.
The conversation that ensues when put in contact with the station manager is telling:
"An Oberlin graduate, Lena Dunham, wrote a memoir where she claims she was raped as a student here. We're checking into the details of the story," I told her.
