By definition the answer you think best is the answer that all of your skills and all of your experiences guide you to. I’m saying you have an obligation to fight for what you know is the right answer. There is nothing ethical about allowing people to make decisions that you believe will be catastrophic. You are being paid for your expertise — don’t accept money if you are not willing to do what you can to ensure a good outcome.
This has nothing to do with having a debate in a meeting, indeed, often the best strategy is to avoid the meeting altogether.
Yes, agreed but that is what I also wrote, you should prevent catastrophic outcomes. I did not wrote anything what you implied in previous comment. I only implied that there is many technical decisions which are nowhere near to catastrophic.
Like picking tabs vs spaces, I am not going to fight about it, it is not a decision that will make any difference for product.
