It was a personal attack, and its not "disrespectful" to state an opinion about a conversation, I am allowed to have those.
False. You made a personal attack against the participants in this forum and then I told you that behaviour wasn't acceptable. If you hate this forum, find it boring, repetitive, etc., just go somewhere else instead of coming here and slagging off the people who use it.
Your use of the laugh react in a mocking/ridiculing way is also beyond the pale for civil, respectful discussion.
