International Day for the Elimination of Racial Discrimination:

Pal,
There's a genuine case to be made against discrimination in general.
Discrimination, whether on the basis of economic, geographic or sexual attributes can be really bad.

However, discrimination on some level is really nobody's business, no matter how so undesirable. And just so I don't bore you with plenty talk, just read the illustration below and see the whole of the point I'm seeking to make:

A blackman drives on the streets of NY and has an inscription on his black car: 'blacks only'. And down-town in Accra, Ghana, a whiteman drives in his white car with the inscription: 'whites only'.

So Pal, inasmuch as discrimination and for that matter racial discrimination is not desired, it cannot be right to forcefully prevent a private person from preventing people of any one race from having access to his/her private property. The best you can do in such cases is to plead for respect.

indeed, it must be abundantly clear that the mere desire to want to eliminate racial discrimination must not be misconstrued for actions aimed at criminalizing the rights of individuals to voice out their disgust for any one race. A whiteman must be free to call a blackman monkey if he so wishes to be that primitive and a blackman must have the freedom to call the whiteman cheese! That is undesired but that is mutual respect.

have a happy International Day for the Elimination of Racial Discrimination.
