I haven't seen things contrary to my faith written in smoke in the sky. However, what about the various similar things that I have to see, either on a daily basis, or on a fairly frequent basis, or anytime I make a road trip to WDW, which are contrary to my faith?
The billboards advertising Cafe Risque as I drive down I-75 through Georgia, just to name one example.
I could also think of other billboards along interstates, or maybe just along the roads as I drive through town, advertising cigarettes, endorsing political candidates that I don't like, or expressing other opinions which I disagree with.
These things may not be written in smoke by an airplane, but they are much more permanent. While the smoke dissapears within minutes, these billboards are there until someone takes them down and are therefore, seen by more people over the long haul.
So how do I feel when I see these things? I'll tell you one thing...it sure doesn't ruin my day. It's all part of living in this old world; you're gonna have to have things "thrown in your face" so to speak...if you want to consider the simple presentation of an opinion or idea as being "shoved in your face"...which I don't. There are billions of people in this world, each with opinions and worldviews, and we are all entitled to express ours.
Nude women dancing around like whores in front of perverted, deprived men at a bar goes against my beliefs, but I don't get my panties in a wad everytime I go to Florida and see advertisements for that place along the interstate. Sure, I think it's sad that humanity is so depraved and that places like this exist and that they are advertising it like there's nothing to be ashamed of. And some may argue that my lack of righteous anger towards those kind of places is indicative of my being de-sensitized to things like that.
But regardless, it's like this folks: we all live in this world and have to come into contact on a daily basis with those who think differently than us and have a different opinion than us. If the simple words "God loves you" or "Jesus" is enough to get you riled, then there's something wrong with you. Maybe you've grown up in a bubble and haven't had a chance to venture out into the world and discover that there are others who have a differing opinion than you, such that the mere sight of someone else's worldview throws you into a tizzy. But all it is is someone expressing their opinion in writing. It's hardly infringing on your rights at all.
So, as I have already said, if someone decided to sky write something about Allah, I don't think I'd be offended at all. The rest of my day would progress the same as planned and I would still be at WDW having a good time. I really don't think I'd be spending the rest of my day stewing about how I had to see something in the sky that goes against my beliefs. With thousands of people walking around the parks, chances are that there is already plenty down on the ground for me to see that goes against my beliefs, whether it's language I overhear that I find vulgar, or someone's T-shirt, etc.
