The poster you are referring to criticized your confrontational first post, as did I. He then went on to criticize the video itself, participating in the debate you want.
You need to decide on the purpose of you posting here. Is it to discuss the merits of mirrorless and whether it will have an effect on the Pentax brand, or is it to complain about members ?
So far you have managed to upset a lot of people and what could have been an interesting debate is in danger of being lost.
Forums work by folk engaging with each other. If you wish to complain about members perhaps you would do better to take it straight to a moderator or forum owners.
