Freedom of speech like every combination of sentence with freedom is totally misunderstood by some individuals.
As I understood, there is a trust system on this forum where any user, including newbies like me with no story on this forum, can tag anyone. This is the freedom of speech! But it doesn't mean that I can spread my laws on anyone. I have my own laws, you have your own laws but we shouldn't harm each other and we shouldn't abuse our capabilities because of freedom of speech.

The freedom of speech is even limited at some point but it still is what it means.
If I couldn't give trust to someone on this forum and only certain users would be able to send trust, then this wouldn't be a freedom of speech.
