Yeah, people are way too sensitive sometimes. There is no need to hide your views and use certain words only in private (or hide behind a computer screen). Feel free to express them publicly throughout Toronto. Be open and honest, I am sure plenty of people will appreciate the candour and return your views and words in kind.
Also, I know they are just words, but Cracker, Whitey, Twinkie, Manja Cake, Ghost, Redneck, Hillbilly, White Boy, Slim, Snow, White bread, Honkey, White Trash (with poor or “poe” added) et al. can be a tad offensive for these virgin ears.
