Is it Appropriate to reveal to Co-workers that I frequent and enthusiastically participate in Conspiracy Web Sites?

This question regarding pornography websites is basically a no brainer, but is my participation in a web forum like GLP something that I would want an employer or co-worker to know about me?

I usually stick to forum's about the economic meltdown and foreign affairs, so it would seem that this type of activity would be considered a positive personal attribute or interest; considering my work is somewhat related.

But with all the sexually provacative, homosexual bashing, hate threads and general silliness, would I be putting myself in an awkward position by revealing my presense here or letting my boss know that I visit the site using the company computers?

Do most people who come here keep it a secret from family and friends?
