The only way in which they were similar is that both circumstances are unpleasant incidents caused because of the colour of people's skin. That makes them racist incidents. Nobody, but nobody, on this thread has suggested for one moment that what you experienced is in any way comparable in weight or offence to black or Asian guys being abused with the terms you censored. That doesn't mean that they're not racist.
Those two examples I gave yesterday of an Indian MD not employing white people and Asian cricket teams not welcoming white players or making them uncomfortable are both real. They are also very obviously examples of racism.
I don't know, if the asian team has excluded white folk because they want a team where they (the asian folk)
aren't excluded, that's not really racism, is it? That has happened all over the shop, and was the main driver for the 'segregated' teams I know of. It's not even really prejudice, is it? If it is because they were excluded from other teams. Similarly i have known some asian bosses who have said they don't like employing white people because white people don't like having an asian boss. They may have been talking bollocks, I've no real way of knowing, but it fits with plenty of experience, sadly.
Of course there will be examples where there is clear discrimination based solely on wanting to exclude people 'not like me' or even because white folks are devils, or some other such bullshit. And that is divisive, racially prejudiced bullshit. Which, tbh, I wouldn't bother being pedantic about and saying 'well, it's not
actually racism, because...' because it is so bloody close, that it isn't worth the effort.
In the case of some kid going 'gammon' or 'honky' tho.... it's just a whole different ball game.
