Seriously, gather some like-minded people from your parish, study the relevant documents, have high-ended dignified conversions with your pastor concerning any continuing liturgical/other abuses, document said efforts and failures for corrections (if necessary).
In other words, play the dialogue game over time - leaving your emotions in check. Then, if necessary, write to the new Bishop with your concerns and documentation. Things might start to change then!
"Other abuses" could include this speaker (Priest). You have to be intelligent in this process though. The Bishop is still new and learning the Diocese. Well thought out and documented critiques from sober and faithful laity could help him out!
