I think political change can also happen outside political parties strictly speaking. There are a host of places where people can become socially active. Movements have emerged and people can get involved. It is also possible to take up various causes. That way, people don't have to toe a party line or principles they don't necessarily agree with. It's very hard for young women to join political parties governed by very strict guidelines that aren't right for them.
