Where can you meet like-minded people? You can go to local "WeareChange" meetings - that's a start. Check out the different 911 Truth groups for meetings. They are everywhere.
What is the real story behind 911? We'll, you can start by reading here: 9/11 Material & Researchhttp://forum.prisonplanet.com/index.php?board=18.0
There are a lot of 911 Truth chapters in major cities. Google your city with 911 truth and we are change and see what comes up.
A new social network should be out soon that will allow us to connect via meetups, but there is Facebook in the meantime. MySpace might have some of that too, if anyone uses that.
Also, join and support the campaign for Ron Paul or a similar-leaning patriot. Chuck Baldwin is another good option.
As for the real story behind 9/11, basically it was an Illuminati job, contracted out to the CIA and Mossad. Basically the zionists did it, whether "Jewish" or "Christian." (I use the terms lightly). There is a strong masonic connection as well. Al qaeda, which means "the file" in Arabic (among other translations), is indeed just a CIA file and Osama bin Laden (real name Tim Osman) was their patsy whose corpse they brought out post-mortem to desecrate to boost Obama's approval rating.
As for Obama, he is an illegal Muslim hardcore leftist plant and likely the bastard son of Malcolm X. Ever look at Malcolm X's wikipedia entry, look at the photo. It'll blow you away.
