Gender Fluidist

Someone who believes gender is fluid (capable of changing based on how one identifies vs societal norms or biological sex.) Much like flat-earthers, they often have their own form of pseudoscience they utilize to argue their beliefs. Gender fluidists will often resort to tactics such as invalidation (discrediting someone's opinion based on how one feels about them,) objectification (negatively labeling someone with a derogatory or collective term) or trivialization (making someone's concerns (valid or personal) out to be ridiculous or ill-founded) in order to argue their beliefs; 'radical' gender fluidists even going as far as justifying threats and violence in order to defend their beliefs. Gender fluidity is a major concept related to the trans rights movement, and the discreditation or disbelief of it is often seen by those who espouse it as a form of 'bigotry' also referred to as 'transphobia'.
