I might agree with you if so much in modern politics wasn't underpinned by faith based ideas that actively make people's lives more difficult than they need to be. I'm very "live and let live" but the RC is as much a political force as a religious one.
While you say it's adherents are "free to choose" you overlook the psychological hold the church has over them, and which translates into actions that harm non-believers, and themselves. Makes a bit of a nonsense of that "alleged" free will.
And a resurgence in religion is being noted, as often is in times of turbulence and insecurity. Using "God" to rally the masses in political directions is a dangerous game, as can be observed in any extremist situation.
If you are indeed an atheist, do you agree that religion should have no place in politics?
The RC church and the Evangelical mega churches in the US have immense resources, and the ears of politicians. The latter are already trying to gain traction with Reform, (pro-life), and have vested interests in "Praying for Armageddon". Various other religions have world domination objectives.
No-one should be persecuted or denied their beliefs, but when they cause harm to others, and meddle in politics, we're on a rocky road indeed.
