Community is a word you hear a lot. It's invoked by politicians and speakers frequently, every day. What does it actually mean though?
Community is a feeling of commonality; a sense of being a part of a group; a common bond. It could stem from geographic location, common interest, family, group membership, affinity for a particular kind of music, hobby, sport. It can stem from almost anything multiple individuals have in common.
The term "community" can also refer to everyone who shares the feeling of community based on the same thing, i.e. "the skateboarding community". Often it's a combination of many things and each individual can feel a part of numerous communities.
The important thing to keep in mind is that it originates as a feeling. It can be a good feeling. It can be an efficiency as well. One can direct messages at a particular community (target marketing). One can get questions answered more quickly and reliably if one knows which community to access for help.
It's important to note that neither feeling nor the group is a person. Community has no property ownership, no vote, no rights. How could it? You can't speak directly to "community". It's not legally liable for anything, anywhere, ever. The individuals within it may be, but "community" is not.
Community can be enjoyed, employed, reinforced, amplified, but it should never be served. The degree to which you indulge in any community is entirely your business, but you owe "community" nothing. Don't worry. It's not a person. It has no feelings. It wont be upset with you if/when you choose not to engage, and it will still be there if/when you decide to go back.
Fun experiment. Try to be aware whenever you hear someone use the word "community". See how many times it's used in the context of asking or suggesting that you give up some of your time and/or money.
