The homeowner refuses to be drawn on why he hung the flags there

Neighbors slammed the flags as inappropriate and asking for trouble

A homeowner has sparked outrage by inexplicably hanging both a Nazi flag and a Confederate flag in his front yard.

The controversial symbols, widely seen to be racist, appeared outside the property in Flint, Michigan, a month ago.

As time goes on, and the unidentified resident refuses to be drawn on it, neighbors are increasingly confused and angry.

'I don't think it's a good idea,' mother Melissa Yancy told MLive.com as she passed the property with her daughter.

'He can put up a Don't Tread On Me flag,' said another neighbor, Mike Woody.

Frances Gilcreast, President of the NAACP Flint branch, slammed the bizarre situation as inappropriate.
