Why do(some of) those who pray feel it should be forced upon others?

I am getting so sick of this thing in Texas (my Texas relatives are blowing up about the injustice) of taking prayer out of a graduation ceremony for a public high school.
Someone sued and won. Everyone is saying “majority rules” and “why can’t he just not pray why we have our prayer time”
I do not understand how they cannot view it from the other side. I completely get their argument. They think the student should just sit in silence and endure it since it’s “not hurting anybody” and “prayer is good for you” blah blah.
But why not view it as not having prayer and religion in a public school and pray on your own time?
Here’s one article on it: state rep trying to restore prayer
