you're not alone - i sounded like a nut to my nephews and nieces (my age) a few years back, they'd refer to me as a "conspiracy theorist", now they acknowledge it hands down.
a couple of months back i was sitting with them and suddenly asked: was 9/11 an inside job? the "educated lawyer" niece said not sure (she's never bothered to research and doesn't even know what wtc7 is), the nephew who's an estate agent immediately said: of course - everyone knows, even the teachers at uni know.
all the other nephews and nieces and my brothers and sisters acknowledge it too now (i did use to make them wait on the way out while i burned dvds and printed booklets etc at the beginning- what a pest!),
i guess feeling like an idiot with a lone voice at the beginning eventually paid off.
that doesn't just work towards one issue - it gives people discernment and they don't fall for lying propaganda so easily after that, and they are much more cautious of psychological manipulation on tv and newspapers - since they now know that the news media has dropped it's claimed goal of informing people and holding the government accountable, and taken to becoming mass murdering liars with blood on their hands who cover up facts.
it also works towards dispelling the propaganda aimed at Islam among atheists and people of other religions.
so don't feel alone in a surrounding of less informed people - you're one of a group of 1.5 billion - almost a quarter of planet earth's population - and growing - but more importantly - you've got the One who knows everything Who's read the back of the book with you.
universal truth is not measured in mass appeal.
