I am not discussing idealism. I am very much discussing facts as they exist. Such facts are 1.) First Amendment free speech clause, 2.) Political speech protected by the 1st Amendment Free Speech Clause, 3.) People are not taxed on the basis of exercising their free speech rights, 4.) Organizations, clubs, and collective speech, which includes churches, have free speech rights and they may 5.) Exercise those rights like the rest of society.
This is idealism you are espousing. The reality is the 1st Amendment Free Speech Clause permits them to speak on issues, just like anyone else. They do not lose free speech rights on the basis of being a church or belonging to a religion. In addition, people, whether individual or collectively as a group, club, organization, etcetera, may seek to have their beliefs, ideas, values, proposals, and views represented in "the state house" and this is an inherent feature of democracy, a republic, and a representative form of government. Now, to be sure, there should be and is a limit as to the extent, manner, and substance in which the values, proposals, and views of religious entities and people may be represented by the government. However, they have as much a right to seek to have "religious trivia" to be represented in "the state house." The U.S. government is not a government for "some" or a government only for those you specifically approve.
So I repeat my point, exercising free speech rights should not and is not the basis for taxation. Neither should tax exempt status be predicated upon foregoing to exercise a specific free speech right.
This isn't idealism I am discussing.
