It isn't verbal abuse, it's linguistically accurate. Treason lobby references people committing what is, dictionary definition - treason. Are we supposed to stop calling people who steal "thieves" because it might offend them? Or do we use the word because it is proper to it's definition. Never ceases to amaze how people want to devolve language when they're made uncomfortable by accuracy.
Treason
1 : the betrayal of a trust : TREACHERY
2 : the offense of attempting by overt acts to overthrow the government of the state to which the offender owes allegiance or to kill or personally injure the sovereign or the sovereign's family
Nothing here about buying a foreign product. Or cutting loose a whiny low skilled American employee.
"Treason lobby references people committing what is, dictionary definition - treason."
Firing you from your job is NOT treason; it is eminently sound business practice. I sincerely doubt that you could actually give the proper definition of treason under the Constitution.
BTW, I wonder if you work for one of the convenience stores I own. If I find that you do . . . well, you won't be working there for very long.
