AOG - just because a black person laughs at a racist joke does not mean that it is acceptable.
Your logic - extended - infersr that dog owners who enjoy dog fighting mean that dog fighting is acceptable.
The inference that 'he finds it funny, and he is black!' is thew weakest of defences used to defend unacceptable behaviour.
The difference is - if people choose to pay to see Jim Davidson, there is a fair chance that they know what to accept, and have the option to leave if they feel upset. That is a whole world away from this incident, where an action clearly calculated to cause offence has taken place - and the law has been brought into play.
Re. your previous post, where you infer that some people are frightened to post on the AB their views on race - I fail to see how you have reached this conclusion.
If you can confirm that anyone has responded on one of your threads that they would like to agree with you, but are frightened to do so, then i am happy to concur, but i suspect that this is simply not the case.
If people absent their views it can be for a myriad of reasons - simply boredom and debate fatigue registers just as well by its absence as your perceived 'fear' to speak out.
I doubt there are any such shrinking violets on the News section, but as always, I am willing to be proved wrong - if the evidnece can be produced to back up your position in that particular instance.
