Planetary CFO on meaning of "Community" post-Brexit

I've heard quite a few reports in the media that one of the main reasons many people voted for Brexit  was to protect a sense of local community.  The claim is that the sense of community is being eroded or swamped by the rate of immigration. 
This very much depends on your point of view about what "community" means.  Is it a fixed or nearly-fixed set of people in a specific geographic area who already know each other well as neighbours, or  is it rather a concept and an approach to our neighbours, whoever they are?  The former view lends itself to increasing isolationism and protectionism.  The latter view lends itself to being good neighbours to everyone, whether at local, regional, national or global levels - many overlapping and interlocking communities, and ultimately a community of communities, such as that represented by the European Union.
