Yes I do think that society encourages bullying, teachers in school often bully students (shouting, embarrassing the kids, creating class rivalry by getting the kids to compete in who can do better at school work, or in a project, instead of encouraging them to work together and support each other).
TV is a major part of bullying, advertisements of kids looking happy with whatever new toy it wants you to buy, convincing the parents that if they wanted their child to be happy then they would buy it for them. Also adverts going on about the healthy aspects of their food (even though generally it's junk food!).
Bullying in work happens a lot as well, trying to get the credit for things to look good for the boss, enjoying it when others fail or make a mistake because it makes you look better ect.
Even team building exercises are usually with one team competing against another. There's no sense of unity, everyone is trying to get themselves ahead of everyone else.
I also think football is a bad influence for bullying, a lot of supporters for different teams absolutely hate each other just because they don't support the same team.
Also I think magazines like Zoo and Maxpower bully girls into thinking if they don't look like Jordon (and be a six 6 with DD breasts, tanned skin, wearing a tiny skirt and low cut top and enough make up for a year) then they aren't attractive. It also makes girls think that they HAVE to be attractive, and that they're main purpose in life is to look pretty for guys.
That's just what I think anyway, bullying is a part of most aspects of society; games, school, work, shopping, neighbourhoods (if they're snobby they won't talk to the person with the untidy garden ect), parents (eg if one parent wants another to look after their child for a day or pick them up from school and they can't they are excluded from the parent group ect). It's everywhere lol.
