Gay Marriage Supporters' Patriotism Questioned

The image seems pretty innocuous—a row of older houses on a side street, their clapboard siding shining in the sun, a lighthouse peeking over rooftops in the background. An American flag flies from a house in the center of the photo, while houses to the left and right of it have orange signs staked in their front yards urging passers-by to vote down on the constitutional amendment writing a ban on same-sex marriage into the state's constitution.

To Sen. Dan Hall, the GOP incumbent for state senate in Burnsville, Savage, and Lakeville, the scene is anything but bucolic. 

"Why is it you never see an American flag where you see a Vote No for the MN #Marriage Amendment sign?" he tweeted on Monday afternoon, alongside a link to the photo.

The photo appears to have been taken on South Lake Avenue in Duluth, near the iconic Lift Bridge.

Hall hasn't yet elaborated on his comment with subsequent tweets.

Inevitably, calls will start coming from some quarters denouncing Hall's comments as anti-American and repugnant, but who's right here? Is it ok to call our political opponents "anti-American?" What about if you think their policies or ideas are actually dangerous to the health of the country?
