Apply: You cannot do any community development work unless you have the movement of the community. If community members are unable/unwilling to see a 'problem'- is it a problem? If they are unwilling/unable to accept that there is an inequality, then you haven't really gotten a basis for a community organization movement. And individuals are at different levels of conscientisation. You need to take this into account- not everyone is going to be on board right away. There needs to be empowerment among the subordinate group so they don't feel their efforts are for naught. And sometimes the group in power has honestly no idea what they're doing is causing inequality and if you don't approach the issue correctly (i.e. if you ambus the group in power) you could cause negative backfire.
Adapt: Social justice education can be fantastic for young adults- for example college students. Some universities offer programs- however in the grand scheme of things only a small subset of students is fortunate to go through such education and training. That aside, in social justice education you have to be very careful about where people are on the scale of consciousness of who they are and their privileges, etc. In fact the education and training programs are geared around that self-discovery. And once people are able to identify where they are, they may be more fully able to understand the inequalities imposed on other groups. In addition, they may be able to identify that a problem/inequality isn't a lost cause. If you can rally enough support you CAN make a stand and challenge a dominant group.
