Abstract conversation is often belittled by people engaged in it. It's seen as worthless, the topics impractical or the goals unattainable. "Back to matters at hand", we say after a deep conversation- "What's for dinner?" I think its the same feeling you get after discussing an obscure hobby or pastime with a group of friends. You sometimes feel self-critical afterwards. I believe it's the desire to fit in with a larger group that can keep us from indulging properly in our unique interests. Just as much as Magic the Gathering or video-gaming, philosophy can be a guilty pleasure. But it's the guilty pleasure most influential to achieving harmony, peace, or any whichever human ideal that our race is supposedly striving for. 

Maybe 98% of your community does not have the interest and/or ability to think critically and abstractly. They might find that what's for dinner is a real issue, more important than contemplating some big idea. Don't be fooled. Use that big head of yours and put things in perspective. Guilt free mother fucker.
