It's as stupid to apply any supposed remedies to Swedish-Wisconsinites in rural Wisconsin as it would be to screen them for sickle cell anemia. But under the guise of political correctness, that's what liberals advocate.
True, disease vector control is key, but it can't help as long as so many deliberately cover their eyes so that they can not see.
