Turn down your condescension a notch or two . . . perhaps you'll learn something instead of preaching.your politically correct doctrine.  

Merriam Webster defines the "ize" suffix to mean "cause to be or conform to or resemble."   I, for example, am white. No one caused me to become white, or to conform to white or to resemble white.  I am white - my race is white: I wasn't converted to white through racialization from some other race I was previously.

Hence, a person can't be racialized.  They might be persecuted, ill-treated ro victimized or any number of other things due to their race, but there is no Pygmalion transformation of one race to another as a result of a process called "racialization."  

Does that help your understanding?
