A What-If Speculation

A suggestion for an alternative religion clause of the First Amendment:

Neither the United States, nor any subdivision of it, shall ever be construed to support, endorse, or be founded upon any religion or religious principle; nor shall the government intrude upon the free exercise of religion so long as such exercise is injurious to no one; nor shall any religious institution participate in any election campaign or public vote. The United States shall be a secular nation with separation of church and state. No religious test or affirmation of any sort shall be required of any employee or official of the United States government, nor of any state or other part, nor by any entity receiving federal funding.

On the other hand …

• What would “nor shall any religious institution participate in any election campaign or public vote” have done to the Abolitionist movement?
• The phrase “…nor by any entity receiving federal funding” might produce problems for organizations that pay taxes and have to compete with other organizations that are allowed to accept federal funding that helps balance the taxes.
• The phrase “…so long as such exercise is injurious to no one” might be interpreted as allowing lawsuits by unemployed Real Americans against people sheltering illegal aliens.
