Groups - conforming to set "laws" of that certain group (could be social groups, family groups [rules of some traditions/cultures], etc)
- having boundaries to how you present yourself.
How are they stified?- e.g. if you belonged to a group that says NO YOU LOOK UGLY IN PINK WE DON'T LIKE YOU WEARING
PINK, and you like the colour pink ... you wouldn't dare wear it right? You wouldn't dare defy their opinion due to the fact you'd be outcasted yes? Maybe wearing the colour pink = a part of who you are (identity), something that builds your sense of self. You'd have to hide/discard this part of you just to conform to this group that hates pink.
I think you would have already explored what makes up an "identity" in class.
One of the points would've been that you are born into a certain family and you can't choose this. The cultures, lifestyles that you are exposed to influence on who you develop to be. This group "family" both helps you become a certain person, but you can also look at it as stopping to from becoming someone totally different.
Religion is something you could talk about too. It's a group of a sort and it does set up boundaries.
If you're thinking about going against that prompt (certainly acceptable to do so in a persuasive form plus the topic says
sometimes so in an expository essay you could explore this) you could say something like...
Belonging to a group helps a person develop their sense of identity as the laws and boundaries that come from this provides as a guide/direction to who this certain person will become. So here you could say having a group doesn't really "stifle", it's a part of developing an individual's identity.
[A "just sayin'" section of Toothy's post which is optional to read, move on if you don't want to spend extra time reading about something a little bit irrelevant to this thread.]Anyway, what I found with context was that everyone thought the introductory bit of it was boring as hell. (i.e. defining what constitutes "belonging", "identity", making lists of problems that affects I&B etc). The people who struggled to write the essays later on were the ones who kept whinging about how mundane/slow/braindevouringahhhh it was at the start ... they pretty much found it hard to dig up ideas for each topic.
