Was I in the wrong?

I just got the most unhinged message from a parent about how I made her daughter upset and shouldn't be a teacher all because I wouldn't do the game dirty Santa for my 5th grade Christmas party.

This mom told me last week her daughter loves dirty Santa and I should do it for the Christmas party. I had already had games like pass the present etc. But dirty Santa is one that I knew my class couldn't handle. I've had some 5th graders that I feel were mature enough for that game. This isn't one of those classes. If I thought a majority of the class could and just one or two would have a fit, then I may have considered it but is that this class has been hard and I knew they can't handle a game like that.

The mom was saying how in pass the present there would be losers so what's the difference. My point was it's not the losing part that they can't handle. It's the "stealing" part in dirty Santa. I know my class and know it would cause too much drama. I said maybe we could do a different version where they all pick a gift based on numbers and at the end they can trade but I wasn't doing the stealing part which the mom thought was stupid.

During my Christmas party yesterday we did play the version I came up with and her daughter got mad because there wasn't any stealing and nobody would trade and she kicked over the trashcan so I sent her to the office. The mom has sent me this unhinged message about how this is my fault and I should have played it the right way and if kids got upset they got upset. Was I wrong here?
