Yeah, me too. Good UV filters are the way to go. I personaly use 3 of them, stacked, because it's known that 1) they don't degrade image quality 2) offer protection from lots of things 3) ALSO protect from UVs (amazing!), and everyone knows UVs are bad, doctors say so, and if they say so for myself, it must apply to my lenses, right ?
I don't know if I should interpret that as a joke or as sarcasm. If the second - you're entitled to your own opinion and beliefs - it won't have any impact on mine. 
I know for sure the front element was saved from scratches when I stumbled on a trek, banged the hood loose on a cliff and dropped the camera that ended up lens down on a rock. The filter was scratched deeply but the lens was unhurt. That's enough of a personal experience for me to know I want filters on my lenses. They can be taken off if I believe they might cause a problem, like when shooting at night with strong light sources in the frame. In most other situations there might be a small difference in image quality but I have never been able to see it in the pictures.
