i agree with you in totality, the moderator misuses his block button here, at his whim and cause of his own mental block.
Blocking divergent views defeates the purpose of any board.
I have seen abusive messages displayed here, while my message with other side of a story were blocked.
The moderator did care to respond back to my email request to inform me the reason of blocking my message, that did not have any offensive or abusive content.
