You are right that both prudence and pragmatism are in short supply and i see it here in Australia with the Aboriginal Voice referendum – Lidia Thorpe-style activists don't understand that the ordinary person will be crucial to the outcome, yet we are still hearing stuff like "always was, always will be, Aboriginal land", "sovereignty never ceded" and "the colony". All of those things will terrify the average Australian voters and kill the YES campaign. You saw it in the USA in 2016: if a few hundred thousand votes in a handful of close states had changed, Clinton would have won the presidency and not calling the rural whites who were leaning towards Trump "deplorables" would have done just that.
