Not One Of Us Lyrics
In a stranger's tear
Looks are deceptive
But distinctions are clear
A foreign body
And a foreign mind
Never welcome
In the land of the blind
You may look like we do
Talk like we do
But you know how it is
Not one of us
No you're not one of us
Not one of us
Not one of us
No you're not one of us
When you learn to divide
How can we be in
If there is no outside
All shades of opinion
Feed an open mind
But your values are twisted
Let us help you unwind
You may look like we do
Talk like we do
-But you know how it is
Not one of us
No you're not one of us

This has nothing to do with the song meaning, but the first time I heard the song I thought of the movie Invasion of the Body Snatchers, where people are reborn as emotionless creatures who all think and act alike.

This song seems to have a similar message to the Genesis tune "Trick of the Tail".

This song seems to be about discrimination. To me is sounds like discrimination against foreigners This song is filled with metaphors.
"It's only water in a stranger's tear"
This suggests that any strangers feelings are unimportant as any tears they cry are only water so they don't matter
"Looks are deceptive but distinctions are clear"
This seems to suggest they don't judge people by how they look but they distinctively know who they can judge. Possibly they distinctively know that he is not one of them and so it is clear they can judge him/her because of his/her nationality.
"A foreign body and a foreign mind never welcome in the land of the blind"
This suggests that any stranger is not welcome where there are people who can't see that there is no difference between them and strangers.
"There's safety in numbers when you learn to divide"
Meaning they go around in a group but to do this they have to divide themselves from everybody else.
"How can we be in when there is no outside"
Suggesting that they are in their own 'territory' but when there is no outside it means they are completely blind to everyone else.
"All shades of opinion feed and open mind but you're values are twisted let us help you unwind"
Suggesting that they claim to be open minded but they 'know' that these people are twisted.
The bridge seems to suggest that is isn't racial as it points out they look the same.
