I'm involved with several car enthusiast activities and events. The car community, in general, never ceases to surprise me at their ability to put differences aside and enjoy each other and their machinery as well as being very generous with charitable events.. One of my favorites is our local Cars and Coffee events (which I hope can start up again by early July). Every demographic, every level of car, and every interest - they all hang out and talk about their common ground.
In the last 10 years I've seen friendships, clubs, and internet forums dissolve because of politics. I like this group because it focuses on common ground, illustrated nicely in the OP's story. I hope it stays that way because politics can turn ugly in a hurry.
