I am missing something, you are saying people on the right mocked Fetterman and now have seen past whatever triggered them and are now seeing a different man, and that's bad? Is that where you are going with this? Because if it is I would think it shows a realization that he has changed and is now trying to work with the right, someone has to try, it might as well be him.
Being concerned about his ability and wishing ill on hi are different things. Unlike the left we try to see the person over party. Naturally, that can't be done with the street level thugs, groomers, pervs and drones.
