I believe Greg Graffin wrote it best.... my answer is at the end,
Hey Brother Christian with your high and might errand,
Your actions speak so loud, I can't hear a word you're saying.
Hey Sister Bleeding Heart with all of your compassion,
Your labors soothe the hurt but can't assuage temptation.
Hey man of science with your perfect rules of measure,
Can you improve this place with the data that you gather?
Hey Mother Mercy can your loins bear fruit forever?
Is your fecundity a trammel or a treasure?
And I want to conquer the world,
Give all the idiots a brand new religion,
Put an end to poverty, uncleanliness and toil,
Promote equality in all my decisions
With a quick wink of the eye
And a "G*d you must be joking!"
Hey Mr. Diplomat with your worldly aspirations,
Did you see the children cry when you left them at the station?
Hey moral soldier you've got righteous proclamation,
And precious tomes to fuel your pulpy conflagrations.
And I want to conquer the world,
Give all the idiots a brand new religion,
Put an end to poverty, uncleanliness and toil,
Promote equality in all of my decisions
I want to conquer the world,
Expose the culprits and feed them to the children,
I'll do away with air pollution and then all save the whales,
We'll have peace on earth and global communion.
I want to conquer the world!
This world is lacking in real empathy. That is my number one. It is incredibly hard to understand what someone feels when your main concern is shoving your belief (or lack thereof down) said person's throat. Behind that, I'd agree with some that have already said "denial/vilification of science", "climate change", fundamentalism, etc....
