There's no free speech irl, you're limited by your personality, your phobias, your einvornment, your mental complexes. There's a striving to say what you want, but it's blocked by thinking about wether it's appropriate or hurts others in 90% of the cases.
On the internet, freedom of speech can be found, but again it's limited by accounts, reddit karma, gold status, popularity. You can say what you can't say in real life, but you're stil supressed by the moderation, by peer pressure (gamification leads to wanting upvotes rather than downvotes), by attempts to not go out of the boundary of the group and scare off people.
Next step would be an anonymous imageboard, the speech is freer, you can say what you want without needing to cover it up with niceties. There are still several rules, moderation can ban you, and the userbase might be hostile to you for no reason other than petty prejudices and word of mouth, generalisations exist without anybody knowing who you are or what you do.
Going higher than that, you have Free Boards (/intl/, /thought/, /am/ and similar), the moderation is non-existent, and with it the posters are more unwinded, there's no "correct speech" as opposed to "wrong speech". You can express yourself at your utmost, without feeling the fear of somebody hating you for it, somebody downvoting you for it, or somebody taking your posting rights fori it. You're being yourself.
Highest form of Free Speech is speech towards God, total unity with the Higher, you express yourself within the wholeness of God and let yourself be one with his Divine Nature. There are no authorities, no peers, no temptations, no pulsions, no bodily functions, no physical limitations. Just your Self and your Speech communicating with God and being accepted wholly, fully, without prejudices and with total Godly Love.
