How Can You Tell if Someone's a Communist?

Ah, this one's a good one.

So I asked,

How Can You Tell if Someone's a Communist?

Are there certain tells that are characteristic of communists?

Do they have some sort of prominent feature?

Is there some sort of a radar you can buy?

Keep in mind at all times I was asking this jokingly, while all the time not expecting serious answers.

The best (4 non-me votes) poster said,

Just look in there I and ask if they love Huu Wong Song's ideas, or whatever that guy's name is from North Korea

I have no idea what the poor chap was trying to say.

"AngryCat" told me,

They don't have horns and hoofs.
The communism doesn't affect your appearence or manners. It's just a set of ideas that a person keeps in his/her head. There is no radar to find out it.

Yes, I know that, but I'm waiting for the person who does believe that communists have hooves and there's special communist radar.

Then this hippie lady said,

everyones a communist in one way or another(called their own set of values)

Which of course pissed off this person,

To the person below me, everyone is not a communist, as communism is a specific set of values.

You will know that they are a communist from speaking with them.

If they say that they are interested in revolution, world unity, class
conflict, and words like proletariat and bourgeisie, it is pretty clear they are a Communist.

Then this clever character said,

Are you trying to find communists or hide your own convictions?

In some American states even the word 'communism' gets the public running to the Republican ballot box.

Touche, man, touche!

Finally, here's my favorite answer,

So sorry you missed the millenium. We are at this present time, in the 21st century in the year 2008. The idea of Communism is a tired one, primarily because the Berlin Wall and thus Communism fell almost 20 years ago!!! You are a quaint relic of a bygone era. You should do one of two things. Either put yourself up for sale at a museum for antiques, or go back to sleep.

This is Yahoo Answers at its finest, people.
