Either I'm missing something....or....(wiper issue)

My wipers sit a little high. So I went to take the nuts off to adjust them. Hey, they arent there! Ok, So I try to take the arms off. I ask myself, why wont they move? I know sometimes you need to bend the arms a little more flat so the hole on the arm is exactly perpindicular to the bolt. (so its centered) Still wont come off.
I have a feeling the previous owner glued the arms on...............
