There are two genders. Male and female.
Liberals think there are hundreds of genders.
There are four races. White, black, Oriental, and Australoid.
Liberals would rather just classify people as white or non-white. Their definition of non-white in addition to non-white also includes whites who are Non-European. They also accuse any person who is non-white or accused of being non-white as being "of color". They try to erase the racial identities of non-whites and lump them together. They would rather say what they aren't than what they are. They think race is binary.
Only blacks are "of color". By calling any non-white or someone they accuse of being non-white "of color", they are erasing the identity of actual blacks who are "of color". Colored and "of color" (the politically correct term for colored), Negro, and black are uniquely black. No non-black should ever be called or accused of being "of color".
