Earlier quoted context omitted.
When America abolished slavery it didn't trigger a protest, it triggered a civil war. Sometimes what's right and what's popular aren't very similar. (but I'm not defending the TTIP)
The United States didn't abolish slavery until after the civil war as one of the Reconstruction Amendments. In a way, the war triggered abolition (or spurred it to happen more quickly), not the other way around.
It's a bit like admonishing the protestors for protesting TTIP before it was enacted. Probably could have chosen slightly more accurate words, but my point was still made.
