That is a whole different attitude. Feel free to ignore them, but if you do enter the discussion then do so fairly. As i said, feel free to celebrate it in whatever way you like. If you dont care about their feelings, or if you think that for whatever reason the "good" effects outweigh the "bad", than by all means continue. It is your tradition, and it is you who decides how it will be shaped and what you want to be part of your heritage. No one should force such a decision upon you, that much we agree to.
