Freedom of religion also means my freedom from your religion (and vice versa). Proselytizers encroach on that freedom, which is why we need serious curbs on those activities.

That means if some bible-thumper mouths off in the subway, they are violating the law, since the subways are publicly-funded and involve limited freedom of movement.

It also means that if a religious organization applies for a permit to hold a rally in a public park, and they meet the usual requirements that any non-religious organization would be required to meet, they should get the permit. In that case, nobody is forced to attend, or even to pay attention, to the religious rally, so nobody's freedom from religion is impinged upon.

It also means that no religious organization should be allowed to hand out anything to children without their parents' consent. Ever. Under our system, where parents bear sole responsibility for raising children (with some modification for schooling), parents also have sole authority in the area of early regligious indoctrination. Authority and responsibility must be equal and coordinate, or a system does not work.
