My default chat box has General unchecked. Sometimes I give it a shot if I am on a relatively unpopulated planet, but even then it is a matter of time before it becomes a cesspool. Fleet is simply vile, and if I could not opt out I would quit playing.
Other games DO keep a lid on the senseless vulgarity, LOTRO for example.
It is sad to realize that " freedom" and "freedom of speech" have become the right to publicly wallow in depravity, vulgarity and obscenity, and that the public rejection of such behavior, or the mere mention of religious or political views that are contrary to them, are rejected as hateful instead of recognized as the very thing free speech was intended to protect.
Society is circling the drain.
