I know it's kind of your thing to prematurely and hyperbolically declare everything and everyone you don't like to be "the worst ever!", and the writers, directors, stars, and producers of ST: Discovery of course understand that they are open to being critiqued (sometimes harshly), but there's a difference between constructive criticism and insults.
Disagreeing with writer Kirsten Beyer's on-set directives to an actor is entirely your prerogative, but calling her a "nutjob" is completely out of line and adds nothing to the conversation. You don't know the motive or context for her decision in the moment or how it relates to the episode, show, or the character, so you're jumping to conclusions and being incredibly rude by insulting her like that. You can say it's wrong or a bad idea based on your limited perspective of the situation, but you can't say she's a nutjob.
Also, you should be mindful that Kirsten Beyer is a current member of TrekBBS, which I think you probably were aware of since you've visited the TrekLit forum (albeit rarely and not in a while) during the time she's been occasionally posting there, and it's been mentioned that she's a member here several times in the thread discussing this situation, so insults of that nature can result in an infraction in the future.
