What do you mean by "quiet change" 25Avalon? If you mean slow change so as not to ruffle the feathers of racists then, in my opinion, it will turn out to be no change or very insubstantial change. For years we have had research findings highlighting the discriminatory, and sometimes life threatening, treatment of non-white people in all areas of public life. Every so often there is an inquiry that confirms these inequalities and makes recommendations, which are often quietly shelved.
Of course, racism is not so overt these days but it still significantly affects people's lives in many ways.
Yes, it would be lovely if we could "all rub along together" but unfortunately it won't happen when some people really don't want to do that and are hell bent on denying there is a problem with racism, sexism, classism, homophobia, etc, etc.
