I agree with you.

If OP doesn't like to be called Q, they should verbalize that to their friend group and the people they interact with. They should also make it known that it is just their preference, and they do not speak for anyone else. But to say that I shouldn't identify as Q because they are offended with the label... OP needs to get over themselves, go touch some grass, and stop trying to police the identities of others in an attempt to push marginalized people out of the larger community of marginalized.
