Sure. I usually approach it by showing why I think the better way is better, rather than just calling them idiots. It have also often happened to me I have reconsidered something I had considered "the right way" for many years, due to a convincing counterargument or example. For example I considered Dijkstra-style single-entry single-exit the right way for years, until I realized that early exits in many cases made functions a lot simpler and more straightforward.
