[Theme: Hueman] Basic formatting not retained on published post

Site: http://www.geekinitiative.com

Problem: When I create a post in visual or html editor, it looks as it should. Same thing with previewing it. When I publish it, the bold, paragraph, and other tags are seemingly not there.

Here is a specific example of a formatted interview that is difficult to read because the formatting is stripped on published view: http://www.geekinitiative.com/business-spotlight-comic-bento-ships-comics-to-you/

I thought perhaps this was due to copying/pasting from an email (gmail) to the editor, so I made a test post available for private view and did some basic formatting. I did not copy and paste from any other source. The same problem occurred, so I think it is in a CSS file but I have no idea how to alter that.

Thanks for any and all help!
