Yours is a not very nice try at blaming staff for the hostility that MtF members demonstrated towards the FtM members. There was a safe area, but as soon as they poked their nose out into the more public areas of the forum, there were people waiting to snipe at them much as you are trying to snipe at staff. Could your words stem from a guilty conscience?
Just because the hate speech occasionally contained an element of part truth did not make it any less hurtful for the FtM members. In the same way that your insult towards the FtM is hurtful to any remaining members. It does not become any less insulting merely because in your not so humble opinion there was an element of truth in the hatred spewed by others against them
