Whenever one talks to employees about another employee that is paid double what they are, statements like this are heard "Yeah, they are really nice/good BUT (here is the hey word ('but'), the word that they believe lends credibility to the bashing about to come) they just suck".
Ever since we go thru grade school, we subconsciously or consciously dislike those that score higher grades, are better at the subjects we fancy or are just flat out teachers pets. Conor is the teachers pet and also school yard bully. Not only is Conor the most transcendental and influential figure in MMA (go walk around Dublin if you feel differently, you won't see hords of people in Rio de Janeiro dressing as the Spider), he is the most talked about, the most loved and also the most hated, the closest with Dana and Lorenzo, the highest promoted and the hardest hyped. Conor exposes the envious and insecure, he is the antithesis of people who say "don't climb mountains, for it is dangerous", he says and does what we wish we could but are too afraid for societal repercussions. He is proof that is you believe in yourself and absolutely dedicate yourself 100% to your passion, you can do it.
For all these reasons paired with his obvious talent, it does not jive well with the quiet but abundant society norm of 'just keep your nose clean, don't make a lot of work and don't make any offensive noise'. Win or lose against Aldo, Conor is here to stay and will retire the most successful athlete to ever compete in MMA.
For your emotional well being, if you are a Conor hater, you may want to dedicate your emotions to something else because he will keep on proving you wrong and you will be left with nothing but ash in your mouth. Nietzsche would characterize someone like him as an 'overman' - he will not fail in the long run and it is better to take note and draw from this once in a generation type athlete than to totally and completely reject him.
