To obamanate v.
To open an argument with obsequious apologetic throat clearing maneuvers which concede much too much.
gerund of "to obamanate."
present participle of "to obamanate."
Opinions on shape of earth differ. Both sides once had a point. Early round earth advocates made claims unsupported by solid data and definitely over-estimated the curvature of the Earth. Christopher Columbus thought that China was as close to Europe as America really is USA. However evidence, which became available long after both sides made their good points, should lead reasonable people to agree that the earth is round.
as quoted by Julianna Goldman and Ian Katz
"round earth advocates['] ... claims unsupported by solid data."
