If I have to say what religion I am it is something like Unitarian Universalist Christianity.
But I don't think having a religion as such is something that has to be compulsory.
I am a big fan of Michael Servetus (1509-1553), who was unjustly executed by John Calvin.
His views were totally tolerable and acceptable. And eminently justified.
All views should be tolerated.
His execution was an example of the evil that inflexible religious thinking can lead to.
