Anyone who disagrees with this inclusive process needs to read the case the Supreme Court ruled on, Town of Greece vs Calloway
Justice Kennedy, joined by The Chief Justice and Justice Alito, concluded in Part II–B that a fact-sensitive inquiry that considers both the setting in which the prayer arises and the audience to whom it is directed shows that the town is not coercing its citizens to engage in a religious observance. The prayer opportunity is evaluated against the backdrop of a historical practice showing that prayer has become part of the Nation’s heritage and tradition. It is presumed that the reasonable observer is acquainted with this tradition and understands that its purposes are to lend gravity to public proceedings and to acknowledge the place religion holds in the lives of many private citizens. Furthermore, the principal audience for these invocations is not the public, but the lawmakers themselves. And those lawmakers did not direct the public to participate, single out dissidents for opprobrium, or indicate that their decisions might be influenced by a person’s acquiescence in the prayer opportunity. Respondents claim that the prayers gave them offense and made them feel excluded and disrespected, but offense does not equate to coercion. In contrast to Lee v. Weisman, 505 U. S. 577, where the Court found coercive a religious invocation at a high school graduation, id., at 592–594, the record here does not suggest that citizens are dissuaded from leaving the meeting room during the prayer, arriving late, or making a later protest.
I don’t know anything about this group but absolutely agree that once you open the door to prayer in what should be a secular govt meeting, you cannot discriminate against anyone, it cannot ONLY be christian prayers.
