You have some serious issues.
Part of the reason I do permit my children to participate in Christmas festivities (and, btw, don't worry, we haven't taken space in a pew yet - my first post was referring to "other" atheists who sit in church every Sunday because their families are sitting there too) is that I want them to learn to understand and respect, rather than fear, Christianity.
If you have a problem with that, then I pity you.
YOU said YOU go to mass as a tourist. Now you change the story and say it's about some other unnamed atheists.
You pity me? Save your pity for yourself.
You insult me, not pity me. You go to mass as a "tourist". You are sickening and insulting.
But hey, I'm glad we amuse you. Next time go to Disney World instead.
