I agree that these are all problems, but the one that bothers me most is the use of "x master race" such as PC master race. Considering the association with the Nazis and genocide, I keep hoping that it will finally die.
Why? What could be more insulting to Hitler than associating his 'glorious master race' with a bunch of gamer neckbeards living in their moms' basements? One of the greatest abilities we have to take the power away from something is to redefine it.
