The billboard calls out a ridiculous belief for being ridiculous. It doesn't say that religious people shouldn't speak; so far, the only person I see saying that anyone shouldn't speak is you.
I don't see it calling out belief as ridiculous.
I had to reference it again to see how you could possibly get this, and (to my surprise) had the opposite reaction.
> You KNOW it's a Myth.
(Okay, so story of Jesus' birth is a Myth (with a capital M, which is both trivial, but weird the billboard does this).
> This Season, Celebrate REASON
(Which without being specific, and is within context of Myth (with a capital M) could be applied to celebrating reasonableness within the Myth. IOW, supporting certain religious beliefs.)
I realize many self identified atheists will categorically disagree with this take, but it is really as close, for me, as claiming (falsely) that the ad is saying religious belief is ridiculous. I'm at least sticking with the words that are stated, rather than flying off in fanciful interpretation of implication and unfounded analysis.
The billboard doesn't dismiss myth; it just calls the Nativity story one. I think the billboard generated as much offense as it did because *Christians* dismiss myth. They were the ones who interpreted "it's a myth" as "it's worthless".
That's a plausible take. I think the one that feels more spot on, and will be what I anticipate as counter argument to what I just noted above, is that in "celebrating reason" we could perhaps set aside the myth for awhile (at least during this season). Then, finally, we Americans (aka American atheists) could have a good ol' time doing whatever it is one does (and believes) to be good winter solstice / end of the year fun.
Also, you're asking a whole lot of a billboard. The general rule of thumb for a good billboard design is that it should have no more than seven words. A person should be able to take in and understand the billboard's message with a glance. This doesn't allow a lot of nuanced expression.
Wow, this one fails on the 7 word allowance. Without understanding what "celebrate reason" actually means, AND that it could plausibly apply to the Myth (with a capital M), I'm not sure one can take in the billboard's message with a glance.
But I do think it provokes thought, further understanding, which billboards (with 9+ words), that are 'just okay,' might do.
