I thought the whole point of making a gang was to unify a bunch of people to complete/protect a singular goal similar to their own. Whether or not they can't fight is beside the point. I can see a bunch of cowards wanting to join those groups because they can't survive without being in one, but gangs usually don't take them. They are too much of an inconvenience or they are a threat by my experience.
Whether or not they understand other peoples views is also irrelevant. There isn't a need to do so obviously, since they are in a group that understands/replaces that need if there even is one. Why does it matter if they don't understand? i am pretty sure they don't care anyways.
What is the true meaning behind gangs today? The essence? If you checked the other posts, the majority of gangs in America were linked with immigrants who bound together for protection and survival. Major orginazations such as the Mafia most likely also had this objective in mind. Todays gangs such as Blood and Crypt probably arn't what they use to be, but making crews and building from there still originates from the idea of gaining protection/survival/power.
There is a reason why most gangs are found in horrible environments and why they still/will still continue to thrive. It isn't a walk through the park in some neighborhoods or cities and sometimes a need for muscle or connections is a must. I know plenty fo people who joined for that reason and who end/ended up dieing just for that reason. That is family to some, and if you back out of the family it is no different than turning your back on them and showing disrespect after all that they have done. I remembered gangs members in Michigan hunting deserters all the way to to california or even out of the country.
There is a reason behind their existence, just most today arn't worth jack.
