It’s not doing it for me. In my case it is McAfee on a Chrome browser that is deciding on the danger posed by a website. Free Republic is all green.
How do you know that it is Google posting the warning? What browser are you using?
I’m using Firefox with Adblock Plus and Ghostery. The warning text is linked to https://support.google.com/websearch/answer/45449?hl=en&rd=1 The search I linked in the source causes it to happen, at least on my computer.
