There’s absolutely no way this is trying to forbid people in the youth corps or whatever it is from ever going to church or witnessing. That would be blatantly illegal and even the dimmest bulb on Capitol Hill knows it wouldn’t hold up. I wouldn’t be surprised however if they’re saying that going to church doesn’t count as volunteer work.
Apparently you need to read the TEXT of the bill.
Illegal or not this is knocking on the door and only awaits the Vote by the Senate.
