What is an adjective for a community (often a minority) which deliberately distances itself from other communities (the majority), potentially for reasons such as discrimination, ostracisation?
You may say:
Due to increasing tensions, this ethnic community has become more ____.
I am specifically looking for a word which conveys hostility towards other communities (violence, etc)
Consider insular, which the Cambridge English Dictionary defines (for both American and British usage) as follows:
... interested only in your own country or group and not willing to accept different or foreign ideas
Another word for isolationist might be autarkic, although I am not sure all dictionaries would recognise the word as an adjective.
Perhaps the word estranged or self-estranged could work.
estranged
no longer friendly; alienated
