I would suggest that the OP get to know the EMsHC that are acting in such an unseemly way. Spend time with them and make friends with them. Grow close to them and learn to love them.
It will help you to overcome getting easily upset if you actually know and are friends with the people that do things that upset you. When people are just anonymous strangers, we somehow feel that it’s OK for us to become angry with them and fume against them in our minds.
If you step outside of your comfort zone and make an effort to get to know some of these people and become friends with them, you will be able to learn just what kind of people they are and why they act the way they do. That’s important for you, as you have come from a different background than them. You must feel like a fish out of water sometimes. It would be good to attempt to understand this “strange new world” that you have chosen to be part of.
There are reasons why they are the way they are, and you are the way you are, and it’s worth trying to discover those reasons so that you will better understand how to deal with people who are different than you.
E.g., perhaps they have grown up with terrible catechesis and they honestly don’t know any better. Or perhaps they are liberal in their theology because they were raised in a very unreligious household and they’re struggling to overcome some of the bad influences that shaped their conscience. Or perhaps they are rebellious against the Church and the Lord because of some personal tragedy that they have never gotten over and has turned them bitter.
You will experience and come to know all about their virtues and strengths, and this will be very helpful to you, because you will come to realize that all Christians (including you) have their strong areas and their weak areas. We’re all on our own journey to heaven, and we meet each other at different points of our own journeys.
And eventually, perhaps after enough time has gone by, you will be able to help them to become more reverent in their actions, even as they will be able to help you overcome some of your personal weaknesses.
And perhaps not. Perhaps the friendship will never take off because you simply don’t have enough in common with them to be able to solidify a friendship. BUT…at least you will be friendly acquaintances, and at least you will have a little better knowledge of these people and perhaps this knowledge will help you to know the best way to deal with their actions (report them to the priest, chat with them privately, pray for their souls, avoid them entirely, or some other course of action that will be helpful to them and you, and will bring glory to the Lord Jesus).
