Two communities in power struggle

I'm on Trump's campaign email list, and got an email today which included this text:

The stakes have never been higher, Friend, and now that you’re on the team, we need your help to send a message that this is YOUR Country, NOT THEIRS.

This was sent as if Mike Pence wrote it.

The setup here is: there are two communities - not one! - and there is a power struggle about whose country it is. There can only be one winner. No compromise. No collaboration. Just competition.
