I suspect this is the Texas legislature "making a statement".
The Ten Commandments are and have been displayed upon the walls of the Supreme Court building ever since the building was
erected (in 1935). They haven't seemed to have harmed anyone, and I suspect that unbelievers pay little attention to them.
While I can see the danger of allowing just any 'religion' to pedal it's wares in public school, I am also not excusing those teachers
who dissuade and cast doubt into the minds of children who come from a Christian family, and the faith which in essence (by it's
universality) , built this nation.
It is also disturbing, since that same Supreme Court building was apparently erected without any complaint...how life and respect
in the U.S., has deteriorated, in just 8+ decades.
No, a religion should not be part of the classroom instruction, other than learning honestly, about religions. Nothing wrong with
excusing students for a time to study the faith of their choice, off site.
However, it is the duty of all to watch that the government does not teach against a given faith, something it regularly does.
The primary fly-in-the-ointment, is that schools are state government schools, now messed with by the federal government.
The best and simplest answer, is for the taxed funds to follow the child..into whatever school best answers their need.
