I think it was pretty brave to post something like that, all the lad was doing was speaking his mind, and i believe this is a place for speaking your mind.
As for the post itself, i think what your saying is that coloured players are "quicker" to be slagged/booed by the bigoted minority we may still have/or have, and that, although you didnt say it, there are white players who have been booed just that these players seem to have been given a bit more patience due to their skin colour.
There could be some truth in this as a possible/actual cause for coloured players seemingly given more stick quicker. All possibles and porbables i suppose, as im sure most latics fans ,who boo/slag players as a form of stick, would boo/slag a player on the basis of their ability while a small minority will do so because of skin colour yet whether this influences the larger majority to then boo/slag a player, i guess we'll never know for certain.
Sorry for the essay style approach to my post, done plenty at uni so its a habit now when im writing.
Hopefully you feel you got value for money as i get student loan lol i knew two years of sociology at college wud come in handy for something too lol
