I'm a Christian, and Pastafarianism is mocking aspects of people who share my general corner of the religious world, and I'm just fine with that. Not only do some of my fellow believers sometimes act in ways that deserve mocking, we often do it ourselves (at least friendly mocking.) And more importantly, by doing things like this, Pastafarians are protecting other minority religious beliefs and practices. The US Army still hasn't quite figured out how to cope with Sikhs wearing turbans (and sometimes they even have trouble with Orthodox Jews, even army chaplains, because they violate critical military doctrines about gentlemen not wearing hats indoors), the TSA harassed them because they're different even before they decided to start harassing other hat-wearers, schools don't let students wear head-scarves (or mini-skirts) because that's Not How Proper American Girls Dress, Muslim-hating idiots beat up Sikhs, the list goes on.
I attended Quaker meetings for a few years, and we'd occasionally get the question about those hats the oatmeal-box guy wears. Quakerism came from England, where it's beastly cold and rainy and Anglos are prone to male pattern baldness, and moved to Pennsylvania and New England where it's also beastly cold and rainy much of the year, and many of them believed in wearing plain durable clothing instead of wearing flashy stuff to draw attention to themselves. But English social custom and legal practice was big on forcing lower-class people to acknowledge the importance of higher-class people, and taking off hats to your betters (especially government officials and nobility) was a big part of that, and Quakerism believes very radically in equality, so Quakers would often get thrown in jail for not taking off their hats around their betters. I wear hats to keep my head warm (as an Anglo who went bald early), and when my beard was longer I could pass for Orthodox if I was wearing a dark suit and a hat.
Back when the TSA were new, they didn't make people take off hats or coats in security lines, but out here at San Jose airport, the main people who wore them were Mexicans wearing cowboy hats heading down to Mexico, and the TSA were the white guys who'd replaced the previous mostly-immigrant screeners, and they decided to make a local rule telling the Mexicans to take their hats off. My first reaction was "if they tried this at LaGuardia the Hasidim would been in the mayor's office in an hour telling him to fire the bigot who thought up that nonsense", but as a Quaker I felt I ought to argue with them because they're clearly just doing it to bully people, and I was successful at making it difficult for them to avoid the bigotry issue for a while.
