hey, drop, just popping in that to this poster at least it was quite clear that you weren’t trolling in the proper sense of the word. You started a genuine rant, albeit based on - as soon become clear - an invalid factual premisse, then gave the thread a humorous if ironic turn. Unfortunately it appears most posters didn’t get the irony, which forced you to make it more explicit. Even more unfortunate is that you chose the word ‘trolling’ which for several humour-impaired members trigerred an automatic response.
I’m sorry that it turned out that way and that you got slapped on the wrist. I fear arguing about it won’t help you. 
Just take heart that, as far as I know your posting style, there is not much risk that you will ever receive a second warning. This just happened to be an accident as a result of the current zero-tolerance policy.
Best wishes.
