It would be helpful if you could enumerate the ways in which his/her statement was naive. It seems to be a relatively logical conclusion that being told or influenced not to say something is restrictive of innate freedom of speech, no matter how seemingly innocuous a reasoning established social or cultural norms are (ie. don't criticize the recently deceased, it's tactless).
