If you could change three things in the US constitution...

[Starbucks Union Thug HokeyPuck]

1. Second Amendment.  DUH!  Make it quite clear what that bad boy means, and certainly make it a bit more flexible to be regulated.

2. Freedom of religion.  We can tell dangerous cults to leave and don't let the door hit ya! 

3. Age restrictions against public office.

1. Enact Equal Rights Amendment extending protections to women and LGBT.
2. Scrap the 2nd Amendment empowering local jurisdictions to enact laws.
3. Tighten 'Freedom of Religion' to ensure that freedom from religion is protected in the public sphere.

What exactly do you have in mind for number 3?

Congress shall make no law respecting an establishment of religion, prohibiting the free exercise or repudiation 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.

I'm not opposed to your change of language, but I'm not aware of Congress attempting to prohibit the repudiation of religion?

Besides,  the existing First Amendment is already being interpreted by the courts as protecting the rights of atheists.

No sir.  Its being interpreted (most of the time) exactly how it was meant to be implemented, to protect EVERYBODY from religion.

Thankfully we have the judicial system to do what it can...
