When someone not from the lgbtq community tries to explain why gay people have rights, or how they are, or anything coming from a non queer person about the queer experience.
when a person of the LGBTQ community tries to tell straight people their "privileges" when they are illy informed about the disadvantages of being a straight person and should SHUT THE FUCK UP!
