Sure most of what religion in my book has done more harm that anything I can think of. But to be honest, in their belief some have created some of the best art, the most beautiful music, and some amazing artcitecture.
Don't forget that Sir Issac Newton was a devout christian, yet he developed the laws of gravity, better yet he invented calculas to do it.
Micheal Faraday was also a devout christian, and his discoveries about electricity and magnatism, are the beginings of the electric world we live in today.
The list goes on and on.

Sure, it is also fun to deface it!

Absolutely. I recently met a couple that had two amazing masterpieces done in oil from the 14th century. They asked me to find buyers for them, but unfortunately their asking price was too high. I've attached a photo of one. Religious or not, it's astounding work.

I have found as I grow more aware of the great damage religions do to individuals and our world, my brightest friends and myself no longer can appreciate religiously based music or art without the grim realization of the history and meaning of these peaces of lovely artwork.

And honestly most of the 'great' art was commissioned to impress...and it still does in many ways. But the subject was the safest at the time of their planning.

Many artists are deeply moved by religious experiences to create. So as a catalyst, religion is ok. The figures can all be seen as mythical. Which they are. Divine inspiration can be an altered state of consciousness. Some really beautiful art has come out of it. And I suppose a lot of it was created by non-religious artists commissioned by the wealthy church. Many struggling artists would take the job even if they disagreed with the subject matter or the purpose. Unlike some cake bakers

It's most definitely possible to appreciate the art, and dislike the theology.

Absolutely.

There is incredible religious art, there is incredible religious music, there is incredible religious architecture. The theistic motivations of the artists involved do not detract from the beauty of their creations.
