Mate how on earth are you not being represented? You're a white (maybe?), heterosexual (maybe?) male, if so you're the most represented type of person that could possibly exist!
That is incorrect. More white males should be on TV in general to represent the demographics of society. If we look at roles in television white working class males are grossly under represented. The topical BBC own studies highlight this as an evidence base.
Posters are making points about proportionality, fairness TV quotas e.g the BBC are aiming for and achieving % of employees from bame groups that go past actual demographic levels - white people are thus being discriminated against.
Diversity does not have to mean less white.
