No, they are not glued on, if you try to get it off from the front it will bend. They are held in with two stud like bits on the back of the badge that go into the frame and are then flattened from inside the frame. A bit like rivots but attached to the badge.
Take forks out and knock the backs off with a large flat head. The badge will then fall off but you will be left with the locating studs on the back. Then you can just glue it back on.
