Why so harsh towards Lucien/Wilson? It was clearly a throwaway tongue in cheek kinda comment.
Bosk1 is right in this situation. It can create a very negative opinion of our forum, which, while not the official one, is definitely viewed as very important in DT land.
Therefore, if people see that comment, it may entice people who would have signed up here to go elsewhere, as well as damaging the site's reputation with the actual members of Dream Theater.
To sum up, it's simply bad for business and it is never good to spread sweeping generalizations ("I'm mad, so everyone I know is mad too!") that can damage the reputation of this forum which we all hold in such high regards. It makes us look childish and immature as a whole, when in reality, while we all joke around once in a while, we can mostly have serious and interesting discussions without animosity.
