#3 Sir/Madam, with respect, I reccomend you do some of your own research, namely on a young Italian gentleman by the name of Gallileo.
Respectfully, the reason why we Athiests sometimes seem intolerant to the faithful, is because we think using reason, logic and analysis, what we can or cannot see before us. For us, to believe in something that has zero basis in scientific fact, has been proven false on several levels (I.e. Gallileo, Turin Shroud etc), and is the cause for the slaughter, rape, persecutuon, brainwashing, child indoctrination, mutilation, torture, extortion, murder and genocide, is completely, and irrevocably foolish.
As for Creationists versus Big Bang Theory, Im an Athiest and I do not believe in either - no Athiest truly believes in the Big Bang Theory, because it is only a theory. Yes it seems far-fethched, but so does the fact that a bearded man in the sky created the world, and personally I would rather trust the greatest intellectual minds and technology ever know to humanity that a 2,000 year old book riddled with controversy and ridicule. I've sadly run out of space for this answer, so I will send you a private message with the rest, please rate as appropriate :)
