This is not a full discussion, but here is my point: the freedom to "do" something also implies the freedom to "not do" something. Freedom implies not being forced. An example some would find not related but I will use it anyways: People used to smoke cigarettes anywhere and everywhere. Even doctors smoked....even inside hospitals. Think about it. Smoke was forced on potentially wounded and dying patients. Now, we don't smoke in hospitals. Hmmmm. Freedom to do something implies freedom to not do something. Freedom to see something potentially objectionable implies the freedom to not see that thing. That is my point, and the only point I will make about freedom in this paragraph.
