Wow. So someone who admires John Lennon is a hypocrite? Does that include admiring him as a musical artist, take or leave his political views? I admire that he stood up for what he believed in and didn't let popular opinion deter him. He was just a person with an opinion like every other celebrity with a microphone is.
Personally, there are things that he has said that I agree with and things that I disagree with. Overall, though, I happen to like his music. However, I am not one who reads into every lyric, and takes everything to heart. "Imagine" is not the song that I was thinking of when I said he influenced me, if that was your assumption, however, I disagree with your analysis of it. I'm pretty sure that by the time he was in his late 30's, and living in New York, he wasn't meeting with gurus and traveling to Tibet. He dabbled in what was popular at the time. There's nothing wrong with searching for meaning in your life if you haven't got it all figured out. I researched the philosophy of Buddhism for a while before completely transitioning to the "dark side". I'm pretty sure he considered himself an agnostic atheist towards the end of his life.
If lyrics are an indicator:
Lyrics From his 1970 song "God" (album "Plastic Ono Band"):
God is a concept by which we can measure our pain...
I don't believe in magic, I don't believe in I-ching,
I don't believe in bible, I don't believe in tarot,
I don't believe in Hitler, I don't believe in Jesus,
I don't believe in Kennedy, I don't believe in Buddha,
I don't believe in mantra, I don't believe in Gita,
I don't believe in yoga, I don't believe in kings,
I don't believe in Elvis, I don't believe in Zimmerman,
I don't believe in Beatles...
I just believe in me, Yoko and me, and that's reality.'
Personally, if I were living in the 60's during a time of monumental change, the draft, and unprecedented human right's cases, I'd be more likely to be a hippie than the alternatives. It's easy to look back with hindsight and judge people who tried to express themselves and their beliefs and didn't have it all figured out.
