She was handing out pamphlets. Talking to people on the street. She was banned from Britain when she went there to interview Tommy Robinson, whom the British gov't has been trying to set up for death for years.
And yes, I am quite familiar with Lauren Southern, and am currently reading Tommy Robinson's book Enemy of the State
Southern is not a terrorist. She has (as far as I know) never committed, planned, or encouraged any act of violence.

Welcome to the age of hyperbole. I fundamentally disagree with Southern on many points, but that doesn't mean that I must necessarily force myself to agree or disagree with all if her ideas as a package nor does it mean having to demonize her.
