If you take that as axiomatic then there is no debate here if we insist on using the term discrimination to discuss this problem. However, if one can arbitrarily redefine words to mean whatever one so chooses them to mean and, in so doing, believe they're redefining what their interlocutor is espousing, then that individual is being truly intellectually dishonest.
Academically, of what discrimination consists and how discrimination is defined, as a word and concept, is still of great debate. Google around for morally relevant differences and discrimination for some sources and further reading. The Stanford Encyclopedia entry on discrimination is a good starting place.
However, in general common usage, the word discrimination is defined as:
> treating a person or particular group of people differently, especially in a worse way from the way in which you treat other people, because of their skin colour, sex, sexuality, etc.

> a : the act, practice, or an instance of discriminating categorically rather than individually b : prejudiced or prejudicial outlook, action, or treatment racial discrimination

>The unjust or prejudicial treatment of different categories of people, especially on the grounds of race, age, or sex.

Note that in common usage the word is not qualified on the power or status of the agent of discrimination.
Unless both one and one's interlocutor have agreed on another definition it is vital to assume good faith and and stick to commonly accepted words and their meanings. If one does not one is at the risk of violating Grice's maxims and, in so doing, losing one's privilege of having others take one's words seriously. Put simply, if it's a new concept, use a new (or qualified) word. A seat at the table is predicated on clear, honest, equivocation-free communication.
I'm sure you're not doing these things purposefully. After all what is the point of advancing a cause if one, through one's actions, prejudices the very people one is trying persuade? It's rather self-defeating.
