maybe ive explained it to many many pro gay marriage ppl and all but one Bay of all ppl have refused to see the inequalities there 
same with the inequalities in parental abortion rights, not one liberal has seen my points.
There are people who feel repeatedly asking the same question is a valid debating tactic. Generally these people feel doing this makes them seem smart/superior because responding with the same question frees them from having to legitimately defend a stupid/weak position.
There are also dumbasses who simply can't understand even the simplest of shit.
It's not always easy to tell between these two types but we probably know what you're dealing with in this case.
