I think that this actually says that it's quite the opposite its treating someone who is of one colour differently from the others white,asian yellow or whatever who have been overlooked, sorry but that is a bad example to set equality is equality not showing preferential treatment to any race of any type
How do you know it's treating Tull differently from any other veteran? It specifies that it's very rare for someone who had served for as long as he did, at the level that he did, not to be honoured. He has been treated differently until now (I would say discriminated against, but I'm sure that would raise hackles), and the petition is seeking to rectify that, and have him treated equally.
This is equality, and this is the example we should set - that he should not be shown preferential or deferential treatment because of his race, but should be judged by his actions, and by the same criteria as anyone else.
