Advice Dealing with Racism/Sexism While Traveling Abroad

Hello! I recently experienced an unfortunate situation where my tour guide made some rather homophobic comments, which left me feeling uncomfortable and unsure how to handle the situation. It got me thinking about how others deal with racism, sexism, or other forms of discrimination while traveling. Does anyone have advice or anecdotes on how to navigate these situations? Whether it's standing up for yourself, finding support, or simply moving on, I'd really appreciate hearing how you've handled similar experiences.
