Not, yet, an arrestable offense to be stupid in public or to harangue other people in a public setting.
Suppression of expression just leads to a feeling of martyrdom and fuels conspiracies. (See? They don’t want the truth to be known.)
Bring back the public speaker corner in parks that used to be common and let the nuts regale each other as they wait their turn to rant.
Calm refutation and presentation of facts is best. Laughter works well also.
