You've got to look at Guardians of the Galaxy if you want some inter-species loving.
If I remember correctly, this was discussed quite a few pages back and Jr Mouse or someone linked to a page that had an explanation of the situation. It went something like, "After the events in Return of the Jedi", the Empire was in disarray and various Grand Moffs (or whatever the Imperial governors were called) managed to retain power over their own areas. Much like the chaos that resulted after the US invasion of Iraq, peace and order did not reign and the New Republic did not immediately gain control over the whole galaxy. The area controlled by the First Order is a hold-out from Imperial times and the Resistance is operating within that First Order-controlled area, like a guerrilla movement. The New Republic is supporting the Resistance but is not openly backing them."
Reading the article helped me to better understand the dynamics of the movie, but it also pissed me off a bit. Frankly, I think that a movie should be able to stand on its own, and not require additional reading of extraneous material in order to understand the plot properly.
