I can't agree with the idea that it is just an aversion to change. That makes the assumption that racialist or racist thinking is an isolated cognition rather than manifesting from a pattern of thoughts which in some areas overlap across other processes and behaviours. Aversion to change is also not one all encompassing process in itself, it can be because of fear, anxiety, values, loyalty, laziness etc. It requires digging beneath the surface.
Why I say racialist (which is not necessarily the same as racist) is because I don't believe there is good justification to see Bond racially. To any frequent observer of the forum, the names speaking out against a black Bond are the most predictable on the basis of the way they talk about all ethnic groups. There is, in my opinion, on that basis, a philosophy and way of thinking around race and ethnic groups that has to be present to be in opposition to a black Bond. Particularly when placed in contrast to someone who thinks differently such as Rando.
