Words can have influence and can come from a place of authority, which does carry responsibility. Words of a president are very different from words published on a random blog by some random person, and different yet again from words published by a newspaper. Some presidents words are opinion, the same words in different context are commands and not acting on them comes at a price.

Context matters. Which is why also different rules apply, and laws exist to guard these rules. DDoS is not an acceptable response in any jurisdiction, no matter what triggered them. We’re not in the Middle Ages, even if some behave like we are. Violence does not justify violence. Unjust action does not justify unjust responses.
