My dictionary defines "critique" as "a detailed analysis and assessment of something." That is not what I'm seeing here, nor is it what I'm arguing against.
I have no problem with people arguing against SpaceX's Mars plans, either on the basis that the plan is infeasible, or that he should be doing something else. I have a huge problem with people arguing against it on the basis that the commenter doesn't like it and the whole idea is dumb.
I just want to see an intelligent conversation.
