I'm to see guys from a decent age acting on such a childish manner. The start of maturity is where you learn to respect the opinion of others and formulate your reply upon that. Obviously that's not the case.
Stop the provoking NOW and to those that feel provoked I advise NOT to engage and go in a discussion. Obviously that will only escalate in other situations.
Or this conversation continues in a respectful and polite way or you don't belong here, the choise is up to you wether to decide if you're old enough to stay.
