Are you with us, or not?

Just what do the DUP want?  They are the Northern Ireland party who are propping up the Tories, but seem to be undecided as to precisely what their stance should be.  On the one hand, they are adamant that they are part of the United Kingdom and as far as Brexit is concerned, for example. they must be treated exactly the same as England, Scotland and Wales.  But when it comes to the question of abortion, where they are completely out of step with the rest of the UK, they demand that they should be allowed to go their own way.  So they want to have their cake and eat it too?
