We all like to think that these "standard opinions" were reached for a good reason, and many times they are. However, we should also keep in mind that a lot of great creativity and innovation comes from individuals who challenge commonly held beliefs. As Siri also pointed out, there are counter examples to the belief that casters are bad.

But let me give some other classic counter examples. At one point, everyone in the world knew, without a doubt, that the world was flat. Once that was shown to be false, everyone knew, without a doubt, that the Earth was the center of the universe and everything revolved around us.

There's nothing wrong with addressing someone's question by highlighting a commonly held belief. If someone comes on here and asks if they should use casters on their robot, it's fine to say no. But you should also take the time to list the reasons why. Look at those situations not as an annoying question that everyone knows the answer to, but as a chance to re-examine your own beliefs and prove them out to the wider audience.

Think of how much faster science would have progressed if our society had done that when talking about a flat Earth, or an Earth-centric view of the universe, instead of waiting for the one person brave enough to defend their position against the hoards that parroted "conventionally held wisdom" without really understanding it.
