Push for it in your state, first. We’re still in the first few cycles using RCV in Maine (I like STAR better) where folks are learning to love it, but there’s no time like now to get that ball rolling. More people need to experience it to shift the national conversation of “whether we should” to “which should we use”
Try finding an open club with Toastmasters and go practice speaking and communicating with folks who are also there to practice speaking and communicating. That kind of space alone may give you the chance to see differences between their interactions and yours, but it’s an incredibly helpful group for so many people who struggle with their communication in everyday life.
