I’m not sure it will help, because it appears ninfan is one of those folks who can’t cope with a logical argument, but nobody seems to have quite addressed his point directly.
The obvious difference, ninfan is that Lineker’s tweet isn’t at all offensive, no matter how you twist it. From what I can work out those complaining are upset that he isn’t being offensive, because that’s what public figures are supposed to be now we’ve all voted to be racists. I’ve tried to work out a correct analogy of flipping the situation, but there isn’t really one.
If Lineker was actually being offensive and racist, there might be a reasonable argument for him being sacked, though I think you’re a bit too dim witted (is that an allowed expression?) to understand the difference.
