Oh dear it seems that you were disagreed with from both sides of the argument - damned if you do..... Interesting that the 3 male comments so far represent indifference, pure backlash anger and jokey objectification, which pretty much symbolizes what men think of feminist issues.
Anyhow, I'm sure that you meant no offence, but it's just that one of the MAIN TOPICS of the vibrant current feminist scene (which you seemed to gloss over) is the sexualization and objectification of women and girls which is worse now than ever. It's huge, it's massive, it ties into consumerism, the celebrity culture, education, the pay gap, everything!!!
Miss World is a manifestation of the so-called ironic retro-sexism that has been hitting us on the head since Madonna started singing Like A Virgin. It's a joke, we're not allowed to laugh at it because we can all tell the difference, but it's still there and it still amounts to the same thing for a young girl growing up in this looks-obsessed world.
I'm glad that you feel happy about your body but there's still thousands of girls that are hating theirs. To not be bothered by Miss World personally is probably good for your health, but to not see the wider issues is kind of disappointing. So of course a few feminists are gonna be a tad miffed.
