You don't have to mention regions and languages if you don't want to give this info out, but it would be interesting to hear.
Where I am, English is a non-native lingua franca among the Greek and Turkish linguistic communities, so a lot of progressive political organising, if it doesn't want to be ethnicity-specific, happens in English. As a bonus, people who just moved to the region and want to be involved, can do it before spending years to learn at least one of the two main local languages to a high enough level to be able to join political activities.
So lately I have been wondering, if I ever have to be abroad for a non-trivial amount of time, how different the language barriers are there going to be. Hence the question.
