One last point:
Freedom comes with the cost of hearing things you will not like.
ABSOLUTE freedom is anarchy, which @Debradelai opposes.
You don't need to worry about the rules here. They're very simple:
Be civilized. Even civilized people can have passionate debates.
You have to be tough in order to be free. You have to let most things roll off your back.
At the same time, being relentlessly and deliberately disruptive is not allowed here.
This place is for adults.
