Fundamentalist Christian church Landover Baptists believe that they’ve worked it out.
Without going into detail about their beliefs, they’re, ahem, a little different from your neighbourhood church. Female church members can get fined up to $200 for using tampons or wearing long earrings. Dancing and failing to get a demon-possessed infant sterilized also attracts fines. Oh, and apparently the Devil is using Olympics Basketball to get teenage boys to masturbate.
They don’t like Mexicans, Arabs, Asians, homosexuals, Catholics, Presbyterians, Mormons, Methodists – basically anyone except themselves, the real True Christians®.
True Christian is marked with either a ™ or ® symbol at various places on their website.
Given that they have their own set of rules for everything they probably won’t care that they can’t legally use the ® symbol without having a registered trade mark (which they don’t have). Although the US Trademarks and Patents Office – sorry, the Devil – could prosecute them. However, they, and anyone else, can use the ™ symbol without restriction, as ™ simply means that the user is claiming exclusive rights and may or may not have anything registered.
Thanks to the reader who alerted me to this.
