Ok, bisexuality and pansexuality does exist and is very much a valid sexual preference. Same goes for asexuality and heterosexuality, all sexualities are valid and should be treated respectfully. Being Bi or Pan doesn't not mean at any cost, mean that the person with that preference is greedy. We all need to normalize Bisexuality, Pansexuality, Asexuality, and any other sexualities that are deemed invalid.
