Indeed there's racism in many forms, shapes, and sizes. At what point should it be addressed, and where? I am certainly no expert here. What I observe in society when it comes to cultural change in general is that often a change is set in by a particular group who trigger a kind of overreaction on the theme by their activism, which in turn leads to severe resistance by others, followed by some 'middle road' becoming the new cultural norm over time. This can take many years.

You saw that with feminism, where at some point many fierce feminists held quite extreme views on the desired role of men in society. The vanguard opened the way, and then during many years feminist ideas started to permeate into every day society. On racism, Black Pete the helper of Saint Nicholas in a yearly children's festivity in the Netherlands, is an example where initially practically no one thought it racist. Until it was made a theme by activists. Now a couple years later about 3 quarters of the country see soot-faced Pete's (from the chimney through which they dispatch gifts), while a third clings to tradition with black face Pete and the argument "it isn't racist, and never was".
