Most, I reckon, are not booing a black man. They are booing Goodes (regardless of colour), or just mindlessly booing because everyone else is. In my opinion Goodes continually overplays the racist cards or is whinging about one this or another.
There are a lot of players (black and white) that I admire.
There are also a lot of players (black and white) that I almost despise.
A player can be very good in his game, but a lousy sportsman. This is the category I put Goodes in.
If Goodes was as good a sportman as Adam Gilchrist then he'd have my admiration.
Having said that, I am not one to boo players, coaches or umpires of any game for any reason.
