I personally think this whole race argument is nonsense.
If Argyle had, over the last few years, had more Non-White players than white players, and more white players had been labelled 'lazy', I strongly doubt anybody would bat an eyelid.
Behind every simple stat, there isn't a conspiracy or a sinister motive.
Granted there is some racism still around in the UK, but compared to the rest of Europe, it's minor.
99.99999% of British football fans will not even think about race when judging a player's application.
