Creating the "Vampires" clan.

The stated topic title: Creating a Clan.
Section - Clans.
There are other sections for free communication.
Night's actions are absolutely justified.

Not entirely correct. The Clan hasn't been created yet. A discussion started about the number of Dark and Light Clans, as well as their composition. The idea arose that there are many Dark Clans, and whether it makes sense to create another one, or if it would be better for the topic author to join an existing one. I joined the discussion and expressed the idea and advocated that the author could join a Light Clan, even though he himself is Dark. And everyone, as best they could, started advocating for their side. As a result, my posts (from the Light side) were removed, while the posts from the Dark side were mostly left. I consider this to be a manifestation of discrimination against the Light forces. Moreover, one of the posts and the topic creator's post were also removed, which I don't understand at all. If the topic creator had complained about off-topic posts in his topic, I would have understood the moderator's actions. I believe that the posts were directly related to the topic of creating Clans or advocating for the topic author to join one or another Clan. So, there is still room for debate about whether these posts were off-topic.
The topic attracted many forum users, and the moderator curtailed the communication by removing posts, which is not good, in my opinion.
