It's not about the gear. It's about seasoned veterans posting questionable advice that could negatively affect the lives of impressionable up and comers who come to forums like this one to learn more about the business.
And no I haven't flown an A380 - just a couple of it's older, slightly smaller brothers which are well equipped to tell a pilot if their gear is not down. Theoretically, if everyone's on the ball and flying the SOP, it's a warning that should never be heard and yet it has been heard, numerous times. Should all of those pilots be grounded for failing to have a perfect memory? The warning wasn't installed just to raise the price of an airplane - it's there for a reason - to improve safety. Just like checklists.
You all can beak off all you like. Frankly I could care less what you think of my opinion. But if you're going to give bad advice, don't complain when someone calls you on it.
