Your anecdote is quite irrelevant and a bit offending. Are you trying to discredit philosophy for some effect?
I, personally, love the study of philosophy and think it's at very least a superb timepass and a hobby. And I duly applaud professional philosophers like Daniel Dennett for tackling important/current issues ('belief in belief' concept regarding theism-atheism debates is a fine example) and for making me ponder. Or Peter Singer, who made me realize I'm a speciesist.
Ten years ago I would have agreed with you. But I have read so much nonsensical, rambling, malarky since that time (and gotten older and more focused on what we can prove rather than how it makes us feel). I read some of this stuff and it truly seems to me that in Philosophy, nobody gets a C in college or is told "maybe this isn't for you" because there is stuff out there that infuriates me with it's total lack of sense. It's like the professors just run the papers through a word counter to see what the grade is.
I can rationalize anything if given the motivation and the time to do it, AND I can do it in any word/page count required by me. That doesn't mean my stupid ideas have any rational merit in the real world.
I think an individual pondering something is fine, but the projection at others of a philosophical construct as fact is akin to religion and just like religion, worthless.
