In my view, it is inappropriate for the editorial board to bash Trump with this statement:
*** "The ruling makes Trump look like the dangerous xenophobe that he is." ***
- In my view it is Inappropriate because of the fact that in seeking support from the public, the CB proclaims the  following: 
** "Civil Beat is supported by readers and donors .....  Your generosity helps Civil Beat do the work that it takes to provide ...... analysis and commentary that gives readers a broad view on important issues. "**
-
"commentary that gives readers a broad view on important issue" -  becomes diluted when showing bias against the messenger instead of exclusively discussing the message.
-
If CB is published for everyone no matter the political affiliation,  then an op-ed of the Editorial Board should discuss the issues and only the issues.
Bashing Trump defeats the purpose of seeking support from the public.
