Merry meet,
I don't participate in the Halloween thing and many other Christian holidays for exactly the reasons posted here, specifically the commercial one! It seems like nowdays, every holiday is out to make money. Halloween (Samhain) is barely over and Christmas stuff is everywhere! When my brothers and I were young, our parents made sure to stress that it wasn't all about what kind and how many goodies were under the tree on Christmas morning. That is the total opposite of what I see today. Maybe that is why I feel much more comfortable with and continue to celebrate the Pagan tradations.
Blessed be
