T-shirt Sold with Holocaust Message, '6 Million Wasn't Enough'

A neo-Nazi t-shirt is being hawked online, with a message bemoaning that more Jews were not exterminated during the Holocaust.

The shirt is emblazoned with letters and numbers ... "6MWE" -- that's code for 6 million wasn't enough.

It's important to note these do not seem to be Holocaust deniers ... they're actually acknowledging that 6 million Jews were savagely murdered, but they feel like the Nazis could have done more.

The logo has a resemblance to the Proud Boys logo, but it's unclear exactly who's behind this disgusting display.
