many gamers especially the adults from bdo take it seriously that they only join guilds with no minors, it was unnecessary to bring up "underage" you could have handled that better and it wasn't their fault to overreact.
How is driving age close to being an adult?
"The minimum age for applying for your learner's permit is 15 years old, but you can begin your driver's education at 14 years old"
There is a reason why the minor age is 18. even that age is too low considering they aren't mature enough until 20+
