I avoided FB for a decade but joined last September to find old friends and those I have worked with in the past. The organization I work for is known to have major restructuring ever 4-5 years so I wanted to network and that has helped.
There is major liberal BS posted on a regular basis and without FB I would not have known how severely warped some of those coworkers are.
FB is owned by one of the most liberal fk'tards on the planet...but it helps to know your enemies.
There are good "private groups" where like minded people congregate including hunting, fishing, motorcycles and cars...some of the fire' members can likely find a groups to share anal sex toy stories if they desire.
There are some outstanding TRUMP/MAGA groups.
