an explanation for why the argument is so terribly constructed. in other words, a reason why they failed to articulate clearly (which is something people are capable of.)
basically if i accept what you are saying as a valid defense, then i accept that argument is impossible because everyone subconsiously chooses sides and is unable to defend them logically. this is simply not the case among reasoning individuals. lunatics are a different story. for those, see UM Philosophy
and i should also add that it implies i should not accept anything you say in the first place, since argument is therefore invalid (subconsious positions are not defendable by conscious reasoning). this is clearly a pointless result. (right/wrong). In which case, the only way meaningful conversation can be propogated is by rejecting it as excuse as i argued before.
