The Vatican has been more blunt recently in reminding bishops that they have the responsibility to allow or facilitate Latin Mass for those who desire it. A number of bishops -- and cardinals -- have shown a bizarre level of opposition toward allowing Latin Masses in their diocese. It really shouldn't be a big deal, and thwarting people for the sake of it has created a lot of bitterness.
Not bizarre, the Latin Mass is the last tie to the Old Church and the Old Morality. Some want to remake the Church totally according to their social views. Think of it as sexual liberation theology.
