Someday, I hope, Americans will wake up and start bringing counter lawsuits against these pinheads for harassment and interfering with their First Amendment rights.
There is no 1st Amendment right or any other right to impose one religious viewpoint on others.
If you consider some religious people as "pinheads", that is your opinion. One man's "true faith" is to another a cult.
The Constitution does not give you or anyone the power of government to advance your faith. You may speak freely, as an individual or private group, but you may not use the police to arrest people as 'infidels' or for blasphemy. You may not use public schools to inculcate a faith belief in prayer. You may not use taxpayer funds to promote one faith perspective.
In every time, priests, preachers, shamans, psychics, palm-readers, astrologers, faith healers, and other non-productives have tried to capture the power of government to protect their status.
Our government is to be secular. Secular means "without regard to faith". It is neutral as regards differing faith beliefs.
Neutral is to be government policy in all public areas. Faith-belief is protected as a personal matter.
There is no 1st Amendment right to forceful proselytization of schoolchildren.
