Because you say so? That exact phrase appears to be in common usage globally. Given that, who's actually out of step with reality here?
The word discrimination describes what an discriminator does. Violence usually applied to what a victim experiences. Surely we can imagine a scenario where someone experiences violence without discrimination occuring.
here is the dictionary definition of violence for your reference.
Thank you for helping my argument, but we can all check the dictionary on our own time.
"It refers to a form of violence wherein some social structure or social institution may harm people by preventing them from meeting their basic needs. Institutionalized adultism, ageism, classism, elitism, ethnocentrism, nationalism, speciesism, racism, and sexism are some examples of structural violence as proposed by Galtung.
According to Galtung, rather than conveying a physical image, structural violence is an "avoidable impairment of fundamental human needs"."
