Whenever there is an argument over whether something should be refactored, dont call a meeting(if it happens now). Just email with pros and cons(to as much detail as possible in a digestable way). Its easier to get lost in a conversation, but with email I feel its easier to convince and once pros and cons are listed for each of them, there is really a no need for argument. Usually something will come out as an obvious solution. Just my 2c
