When it comes to refusing to recognize something, it can be helpful to have a variety of synonyms at your disposal. Here are a few options to consider: reject, deny, disregard, ignore, disavow, repudiate, spurn, snub, rebuff, veto, disregard, discount, neglect, brush off, and turn a blind eye. Each of these synonyms emphasizes the act of actively avoiding or rejecting something, whether it's an idea, person, or situation. It's important to choose the right synonym based on the context and tone of the situation, but having a range of options can help you be more precise in your language.
