From the NYT article:

"...the Stolen Valor Act, which made it a crime simply to lie about having received a military medal or service badge." (italics mine)

“'There would be no constitutional bar to criminalizing lying about one’s height, weight, age, or financial status on Match.com or Facebook, or falsely representing to one’s mother that one does not smoke, drink alcoholic beverages, is a virgin, or has not exceeded the speed limit while driving on the freeway,' Judge Milan D. Smith, Jr., wrote for the majority. 'The sad fact is, most people lie about some aspects of their lives from time to time.'”

I'm imagining showing up to a Clan [example]-sponsored Robbie Burns Night and some toff there insists that all attending present bona fides proving their blood ties to the clan. When I haven't got any, he comes after me later for misrepresenting my genealogy.

As the son of a SEAL (UDT-R 29), I have very strong feelings about those who claim what others earn, but lawsuits are brought every day by petty, spiteful members of a group against their fellows, and legislation like this really could provide a basis for future abuse.
