"Be practical" as a rationale for doing the wrong thing is almost always employed by someone who benefits from retaining the status quo. We need to remind people that "expedience is the *absence* of principle"...
We need to have a society based on clear, well explained principles... because we need to stop digging a whole lot of holes now if we ever hope to get out of them. That means doing the right thing *especially* when "not practical" because it shows structural problems we need to fix.
The common response from institutionalised individuals is "it's too hard to change the system"... Thankfully, we have a very good quote that backs us up... Thank you George Bernard Shaw (updated to recognise that other genders can lead positive change) "The reasonable person adapts themself to the world: the unreasonable one persists in trying to adapt the world to themselves. Therefore all progress depends on the unreasonable person.” https://www.goodreads.com/quotes/536961-the-reasonable-man-adapts-himself-to-the-world-the-unreasonable
@lightweight I have a sign on my desk at work. It says "There is never a right time to do the wrong thing." I try to live by that, but I know I fall short.
@cstanhope we've got to have a clear ideal before us in order to even know when we're not living up to it. We need to forgive ourselves when we fail, as we all do from time to time, but we should never make excuses either :)
