Take a letter
Oxfordians make much of the fact that there are no surviving letters written by Shakespeare as if the fact that the 70 letters of Oxford's which survive give him precedence, Yet in 70 letters, there is not a single mention of poetry, plays, players, theatres, absolutely nothing. No evidence of any connection with Shakespeare's world whatsoever.
If this sounds a bit like an Oxfordian argument disqualifying Shakespeare, it's because it is. Oxfordians can’t make all the historical evidence about Shakespeare disappear but instead they argue that there are no manuscripts and that all the unequivocal references to Will of Stratford are non-literary.
Fair’s fair. If that disqualifies Shakespeare, it also disqualifies Oxford.
The truth is that the amount of detail which survives about Will and his plays is perfectly normal for a playwright of the time.
