You're still not understanding what I'm saying. I'm explaining why I find this offensive. I didn't say atheists should support the revival of anything. But I'm explaining how it looks to people like me when displays like the one in the OP are created.
I do understand you, honestly.
Ultimately, though, I'm much more comfortable in a world where religion is subject to light ridicule than one where it's not, and I honestly think that stance would remain regardless of my theistic leanings.
Likewise, I am more comfortable in a world where political figures are subject to light ridicule for much the same reason.
If I tell a Christian that in my opinion their God doesn't exist, they may find this offensive.
If I tell Christians, repeatedly, that their God doesn't exist, I might actually be counter productive to what I am trying to achieve (which is probably my single biggest concern and issue with antitheism).
And if I replace Christian in the above posting with whatever other religion, polytheistic or otherwise, that you wish to substitute, then I would submit that my opinion remains unchanged.
I don't think their display is particularly compelling, but neither would I want it censored. There are plenty of jokes on tv I don't find funny, but I prefer them uncensored as well.
The issue for me is more around the use of public space. I don't see how it can be used for an anti-theistic display any more than it should be for a theistic display, but American laws, etc, are a little different, and I'm not always across how your Uni system works in any detail.
So in short, I see polytheistic religions as every bit fair game, just as monotheistic, or atheistic beliefs are. But the rules have to be fair, and my initial thoughts here are to wonder how I would react if that display was a pro-Islamic message (for example). Probably not a massive fan, and I'd wonder at the use of space. That's where my head's at with this one too.
