How can you be happy with creationist, homophobic, religious fundamentalist climate change deniers being brought to the table?
We don't know that yet, and honestly I don't know enough about the DUP to comment, but if they have those policies/opinions they are mostly still irrelevant, they are hardly going to be the ruling party.
The key to everything is Brexit and making sure we don't leave with no deal which would be disaster for the country.
