-a public school forcing or coercing children to participate in prayer,
that's just your accusation. As you said, You don't know this coach nor his intentions. You're just assigning the "forcing or coercing" on him.
And as I said, students can be victims of marginalization worse than this.
How about the same coach who also teaches social studies but hates boys who go out for cross country and makes their life hell up to and including giving out worse grades?
THAT goes on 50 fold in schools more than this concern over a choice to not participate in a prayer.
"And most R's will continue supporting the R party no matter what, even if they're among the 60+% who want abortion kept legal, because either they're just going along with the rest of the platform, they can't vote with librulz,"
IOW, the issue isn't that important to them.
