(though like DQ, and for me, the only thin I really like is the traditionally service, it can be boring, but like, it is how you glorify God, it's top notch)
My view is that, what we believe happens during the Mass deserves to have a mystical/reverent feel to it. The ritual/incense/latin elements are warranted, given the significance of the context, imo. To quote the Legend, that's not something to be taken lightly.
The jokey-jokes and acoustic guitars and general informality just feels inappropriate and out of place to me. That said, if that stuff gets some people to the place they need to be in to receive communion, then hey, whatever floats their boat.
It's stylistic, but the ritual does it for me and others, and I think it's pretty easy to see why people are protective of it.
It honestly took me a long time to be more comfortable with the more sing-songy and open ways others do it, because of how mass is structured, it felt so short of actually properly doing it. But agree with you, I think different strokes for different folks is important, we all are after all trying to figure it out, no one is 100% right, and it's all fairly open to interpretation. If anything having gone to catholic mass, baptist, presbytarian, methodist, and lutheran services the thing that always strikes me is what is being said is almost always the same, but how it's utilized rests almost exclusively in the pastor/priest/preacher. Even one catholic church to the next depending on what that priest's hobby horse is can change the general tenor and demeanor of the church they lead.
I think as long as people who do go to church, regardless of their denomination follow the following guidelines everyone is better:
1) You're imperfect, as is the priest/pastor/preacher, and therefore your judgement, and theirs should be seen from the lens of an imperfect person, it is ok to disagree with them and even challenge them, as long as you're respectful.
2) Be wary of churches that value treasure above time and talent
3) Truly find out why you believe in what your congregation is making you believe, Jesus wants you to be part of his flock but I don't think he wants you to actually be a sheep.
4) Have perspective, infighting over doctrine regardless of religion has basically been going on since the beginning of time, there is no grand unified theory and no "right" was to do things, and if Jesus didn't talk about it then it's some dude just freestyling to try and make it seem like he did (Paul).
5) Take and apply those same principles to all aspects of your life, other religions and other people who aren't religious go through basically the same thing morally, mentally, and spiritually.
