Welcome cletis!
As travelover said, just pick and choose the threads that interest you and blow right by those comments that seem offensive or argumentative. There are a lot of very intelligent and opinionated people on this forum who don't have any problem expressing their opinion about anything and everything, including political and religious matters, which can sometimes get pretty heated discussions going.
This is a great group of people and a fabulous retirement resource. You might also go back and read some of the really old threads that are still just as good today as they were at the time. Good advice ages well!
