Expressing an opinion is not promoting an agenda. It is merely the act of expressing an opinion. Everyone is entitled to theirs, as I am to mine.

I see the quote above is being used as an excuse for bad behavior on the part of someone who, as a forum moderator, ought to know better. Accusing someone of being bored and only posting to try to divert the thread to one of their own agendas is a personal attack. But the one who made it is too drunk with power to really give a shit about the rules, because that person knows they will never experience any consequences for their own violation of the rules.
