Society - We Christians Need to Lobby to Expand the First Amendment for our Protection

I just received an email titled:

"City of Houston demands pastors turn over sermons "

http://www.foxnews.com/opinion/2014/10/14/city-houston-demands-pastors-turn-over-sermons/

According to this news story, there is an anti-Christian mood in that poor city.  The government of that city is now persecuting Christian speech that criticizes homosexual behavior. 

The situation, it appears, began with the stance taken by the mayor of Houston who according to this story is a lesbian and that she takes issue with sermons that stress the Biblical take on homosexuality. 

Didn't we have a Freedom of Religion Right in the Bill of Rights of our beloved US Constitution?

Apparently, when lawyers of cities, of homosexualist groups, of atheist groups, and of so-called civil rights groups such as the ACLU, can come after Christians and threaten them with lawsuits in order to silence them regarding what positions they take or if they don't want to cater to gay marriages, then what we have here anti-Christian creed discrimination and we Christians need to lobby to expand the First Amendment.

 Let's look at the First Amendment in its present form.

Amendment I

Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.

From what I see here, the Amendment grants us Americans the right to exercise our religion and enjoin the US Congress from making a law that would prohibit our right to practice it.

The problem though is that the Courts can countermand it.  Lawyers can get around it and prohibit our right to practice it. What's up with this? IF we Americans have this constitutional right to speak our mind without fear and practice our religion, how is it that the Mayor of Houston can prohibit the right to exercise our freedoms of speech and of religion?

If the rank of the US Congress is above the rank of the ACLU and of the atheists' lawyers and homosexualist pressure groups - and if  the Congress itself is prohibited from prohibiting our rights to free speech and free exercise of religion, how is it that they're allowed to trespass upon our consititutional  rights and  trample them beneath their feet.

Now what I'm seeing here also is that if every clause is not spelled out to cover every and any possibility that some weak point can be exploited using a bypass maneuver or backdoor to sabotage the First Amendment, then the First Amendment in its original and current form does not afford the American People with enough protection.

I submit an extension of the First Amendment.

Neither Congress [nor the Judiciary or any of its courts nor the Executive Branch shall make any law, ruling, or policy, or lawsuit respecting an establishment of religion OR atheism], or prohibiting the free exercise thereof; or abridging the freedom of speech, or [of the press or of the clergy or pastoral services] or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.

Not being lawyers but still seeing the eroding of our rights to practice our speech and religion, what will we who face governmental intimidation or bureaucratic harassment have do to shield ourselves in a such a shark-infested environment as the current political system from such ferocious attacks? 

Do we have to sue these people back with Creed Discrimination Lawsuits or what?
