True, true. Every time I hear "Imagine" on the radio, I dissect the lyrics to my very conservative wife, and she kinda rolls her eyes at me for ruining a nice song. As much as I "like" the song, the lyrics do give me a problem, but mostly because they are real stupid. Now, if I thought people were really listening and believing all that cr*p, then I would be worried. But your point is well taken.
I personally can't enjoy the song because of the lyrics. But I generally don't argue about them. Except on FreeRepublic, of course -- where we argue about everything! :-)
Regards.
