My favorite all-time bumper sticker: Keep your religion out of my government and I will keep my government out of your religion

You mean, like in my childhood, where church was where you went to receive info on how to behave in an Xian-like way?

Christians are the worst

Yes but if religion was a private thing, not, weaponized to oppress, justify harmful beliefs and rituals, and infiltrate government, who would want it ? It is because people want those things, that they choose religion as the best way to get them.

Yeah that pesky control thing they have

"Government " is something that should be privately practiced and not imposed up people with sadomasochism capitalism slavery punishments but rather with teachings and counsel. Such can see a difference in the writings of Masonic lodge secret religion racist devil worshipper European invador governmental terrorist Benjamin Franklin's essay pointing out who really are the savages of north America.

"...when old, Counsellors; for all their Government is by Counsel of the Sages; there is no Force there are no Prisons, no Officers to compel Obedience, or inflict Punishment.—Hence they generally study Oratory; the best Speaker having the most Influence. "

First thing, religion is a form of government. So, "religion " isn't, as this implies, something that is infiltrating government but rather contending to be the dominant or higher form or controlling government.

Religions have gotten a lot more powerful and dangerous during my lifetime.
The developments are internationally scary.

If only it were, but it never is. Religions need money, need validation, need to spread like a virus, and can never stay private, no more than a virus can.
