Geez Tim, relax a bit.......those "pro-Trump" cartoons are not that big a deal.  We live in a pluralistic society and there are multiple views on every topic imaginable.  

You write: " But political cartoons are supposed to reflect the thinking of the editorial staff; that’s why they’re on the editorial page."  May I disagree..  The "unsigned" editorials published on the editorial page reflect the thinking of the editorial staff.  The OpEd pieces and the political cartoons (and yes, the Letters to the Editor too) represent the thinking of the writer or artist and are signed by them.    

A responsible newspaper will publish a variety of such views along with the paper's opinion expressed in those "unsigned" editorial pieces.  It's our responsibility as reader/citizens to consider those varied views along with the "factual" side of the news and form our own opinions regarding the topics and issues addressed.  Gary Crum
