It's a thorny issue. I don't think that all activities must perforce be accessible to everyone. For example, I don't object to my friends going on the scary rides without me when we go to the amusement park, just as long as we all do something fun together.

The problem I see here is that the yuletide people are making an effort not to cause anxiety, but supporters of yuletide are undercutting that effort. I think we can learn a lesson from that.
