I (and probably the 2 who upvoted me) misunderstood your use of 'ironic'. I now see that you probably meant it in the sense of 'superficially paradoxical or false, but on closer inspection, interesing'. (I thought you meant it more in the sense of 'incongruous, and consequently suspect'. I.e., I thought you were arguing that it is probably bad pedagogy to advise an aspiring rationalist not to reason about something.)
