I have an example. My disclaimer is that I haven't backed it up with any research, it's just what my environmental science teacher told us, unless he's having us on.
Hurricanes, yeah? We all know they give each one a name. Katrina, Rita, Jeanne, etc.
Turns out that some American lobbying groups have contacted the meteorology authorities and complained that giving hurricanes female names promotes gender inequality and should be given male names as well. They have no choice but to comply.
Similarly, pro-ethnic groups have done the same, meaning that a share of hurricanes now require ethnic names. So it's now hurricane Sally, Tom, Mohammed, Drago, Tamiko...
Odd example I know, but how's that for political correctedness, eh?
