They can call me honky all day long until they run out of breath. The American flag doesn’t “offend” me either.
No foreigners living here, except the liberal ones, would be offended by such a slogan. Japanese is full of silly English, profane or otherwise, all the heck over the place - shop names, restaurant menus, advertisements, and especially clothing. Some dipshit at the Washington Times got a line on the TV show from someone and decided to run with with it, not knowing the first thing about Japan.
