I have taken to calling some members of the furthest left wing of politics “sinister” lately. And KnoxvilleDot wants to know why.
Well, “sinister” means left. Therefore it is appropriate for those on the political left. However, sinister also has connotations of weakness, evil and/or incompetence.
So sinister is perfectly appropriate for those who adhere to the historic party of slavery and repression, which many call “a crime syndicate masquerading as a political party.
