Why do people always throw out the "if you don't like Hazel you must be jealous of her" claim ?

I'm a bloke. I don't like Hazel and i definitely have nothing to be 'jealous' of her for.

The only thing she's got going for her is her looks and to be totally honest i think there's a lot nicer looking women than Hazel out there. She's no stunner, that's for sure, and regardless of her looks she's not a good person and not a particularly nice person either. She was in that house to further her 'career' and nothing else. She said herself that she didn't give a sh*t about anyone else in there. Why bother going on Big Brother if you don't want to meet and experience new people that are different to yourself ?
If you like Hazel then i have no problem with that. Everyone's entitled to like or dislike whoever they want but calling people "jealous" just because they don't like her is just ridiculous!!!
