A classic CureZone troll is trying to make us believe that he is a genuine skeptic with no hidden agenda. He is divisive and argumentative with need-to-be-right attitude, "searching for the truth", flaming discussion, and sometimes insulting people or provoking people to insult him. Troll is usually an expert in reusing the same words of its opponents and in turning it against them.
That's not the same as wearing a shirt and saying, "I get why you'd think it's offensive, but I think it's funny, and it's my right to wear this shirt."
There may be people who wear T-Shirt Hell shirts because they think they're funny instead of because they want to offend people and get a reaction, but that's not germane to the question of whether anonymity is one of the essential elements of trolling. It isn't.
