Just looked it up and the entire first page of searches is about how ‘guys’ is masculine and insensitive to women. I disagree. I think the masculinization of the term is like an unneeded extra filter placed over ‘guy’ but the term itself is innocent. Guy Fawkes was a real person. He did something that caused him to be a symbol of the common person. There is nothing gendered about that. It’s the patriarchal culture that then assumed ‘common person’ refers to males. When I think of Guy Fawkes, it is his actions, not what’s in his pants, that is important. So, while there are many needlessly sexist and sexual phrases in English, I do not view ''Guy" as one of them and, instead, view it as a victim of the patriarchy just like you and me. It isn’t an inappropriate phrase to change or remove, it’s one to reclaim for all people; which is exactly in the spirit of the symbol of who Guy Fawkes is.
