I agree. Conspiracy Theories are easy to believe because they are consistent with the normal behavior of the group that they are trying to apply the story to.
If I hear a liberal, lies, cheats, destroys... then I am likely to believe it before I see evidence. The evidence they then provide is generally a lie or cheat.
I think of Obama's BC. Why was it so easy to believe? Because Pelosi had a duty to verify that Obama met the requirement to be President. She did with McCain but skipped Obama. Obama then hid it for I think some 7 years. We were even told at one point that it was burned in a fire.
Who created the Obama BC conspiracy? It was Obama himself.
Do people still believe it = yes. Because it took him 7 years for it to rise out of the ashes.
If it were not a requirement that Pelosi and Obama had not ignored then the conspiracy would never have started or would have died quickly.
