Gender dysphoria is when your internal sense of gender differs from your gender you were assigned to at birth. Part of the transitioning process includes going on hormones, undertaking surgery and changing names, which can be a difficult process.
Many trans and non-binary people use pronouns such as xir or they/them. Rejecting these pronouns or deliberate misgendering can be upset and humiliating for the trans or nonbinary person, so it is important that you respect their identity.
