It's very simple. T'ai Chi is a quasi-concern troll. For those not familiar with the term, a "concern troll" is one who comments on a forum or blog and purports to share the purpose of the organization, but is "concerned" that its message is being hampered by [insert facts that supposedly hurt the cause] Wikipedia definition

T'ai Chi doesn't quite go the full nine yards of declaring himself a member of, or an opponent of, the "Organized Skeptical Movement." He intentionally keeps its definition vague, and flip-flops on whether he is a member of this movement. Thus he is able (he thinks) to throw mud at folks here without coming out of the closet and staking out a position that he would have to defend.
Hence the occasional thread like this, in which he woundedly declares "skeptical movement? Why, here's one!" But he entirely fails to address the questions that people have posed to him, i.e. what is the skeptical movement, what are its goals, is he a member or an opponent, etc.
It's fun to slap him around every now and then; just don't make the mistake of taking him seriously.
