Us in the UK are not having it. Even some members within the Conservative party and Conservative voters are angry about this decision. The DUP do not represent British rights. They're basically as bad, if not worse than the Westboro Baptist Church from what I've read.
If the Conservatives had chosen any other party to form a coalition with then the British public would have dealt with it but this particular group has extremist views and has links to terrorism. The fact Theresa May chose to have a coalition with them is Conservative hypocrisy at it's finest.
