If you’re presenting your religious viewpoint as part of an official public action/proceeding/display, etc… then yes it is your responsibility to ensure all viewpoints are being shown if you want it to pass constitutional scrutiny. That’s the price you pay for bringing a religious viewpoint to the public sphere. You’re welcome to express your viewpoint as a private individual to your heart’s content in the public, but the second you make the state a party to that expression, then it must make sure ALL religions are able to be represented equally. That’s where the issue lies. Take a recent and classic example, the ten commandments in a public building. That’s fine courts have rightly ruled, but then other religions similar codification of laws have to be given equal treatment or the government has in effect become a sponsor of Christianity. And in this classic example typically the private individuals who introduced the ten commandments in the first place, or the state actor in the instances the state did it at a private individual’s behest, don’t want to bother with other religions so they pull the commandments. As they should. Because refusing to so becomes government sponsorship of Christianity.
