Think harder:
numerous claims of the virus DNA etc. despite the impossibility of such a feat. (Acceptance of the fact that to this day no viral DNA has been demonstrated to be extracted from any cell/tissue or egg culture/medium, any, period, that was "infected" with the "virus")
Viruses are undistinguished from Antibodies, both of which have been demonstrated to originate from almost any cell, and both of which act as a signal to other cells but don't hijack or otherwise corrupt the cell.
