+ trash on Mars US Edition - Today's top story: Ron DeSantis and Greg Abbott pull from segregationists' playbook with their anti-immigration stunts [View in browser]( US Edition | 20 September 2022 [The Conversation]( For weeks, Governors Ron DeSantis of Florida and Greg Abbott of Texas have been flying and busing undocumented immigrants to Democratic-run states and cities, such as New York and Washington, D.C. Outside of the right-wing media ecosystem, the trips have mostly flown under the radar â that is, until DeSantisâ Marthaâs Vineyard-bound flight of Venezuelan immigrants made headlines around the world. Itâs tempting to dismiss it all as a mere political stunt. But historian Greta de Jong sees disturbing parallels â in action and rhetoric â to the way some Southern segregationists dealt with Black citizens during the civil rights era. As part of a broader effort to purge their communities of Black Americans, segregationists put them on buses with one-way tickets to Northern cities in what were called âreverse freedom rides.â âThen, as now,â [de Jong writes](, âthe message was, âHere, you love them so much, you take care of them.ââ Also today: - [Indiaâs ancient stalagmites offer a warning](
