We all worship differently - I believe the crux of it is not give Him worship. It is an act not for ourselves per se, but for God. He should be the focus. It is something He deserves.
However, I am with you in some way on this. Although I am no longer Catholic, some of the older, more majestic hymns such as "Holy Holy Holy" were more dignified in my opinion for who God is. And although I don't denigrate some for being outward with their hand or arm movements during worship, that just isn't the way I feel comfortable when approaching God. Again, I don't demean their approach - but to me, the dignity and reverence of approaching God merits a joyful approach, a reverent approach, and a personal approach.
The sometimes bombastic and frivolous approaches I sometimes see in other churches make me uncomfortable, because I feel there is something in them that puts the focus on the individual, rather than God. But again, the Bible speaks of dance and joy before the Lord, so I don't want to take that away. I try and always remember who God is. Jesus is personal to me, but He isn't trivial, nor should He be treated that way.
I grew up Roman Catholic, but I am now an evangelical Christian
