Claiming implicit bias is a very well greased slope towards a bad end because it lets you say (your opinion is that) someone else's actions show a pattern of whatever-ism and that they are not credible because of it and they cannot defend themselves because their whatever-ism is not consciously applied.

Just because brogrammers want to promote other brogrammers does not make them whatever-ist. Claiming that implicit bias is a type of whatever-ism is just BS doublespeak like "if you're not the solution you're the problem".
