Understand that lad culture is a subdivision of our society and is not contained, it spreads through everything. Advertisements directed at men that show a woman as an object (a games console, a beer bottle, etc) are not only appealing to men within the culture, but also reinforce the idea that objectifying women is right and okay. Our society makes lad culture acceptable.
I like to think of myself as a gentleman. Not in the top hat wearing, Bertie Wooster sense of the word, but in the more general sense. I make an effort to be polite to everyone, and to respect those I disagree with. That's why the discovery of the sites LADBible and UniLAD make me want to throw something through a window.
Whilst I hope that Plymouth University do expel the likes of Jamie Street I have a sinking feeling this may not be the case. It makes me wonder, had the site employed a racist rhetoric rather than a sexist one (although I did spot a little bit of homophobia in one article - wouldn't want you to think the writers weren't liberal with their bigotry) would we have heard by now that Plymouth had terminated their relationship with Street.
