The short version- Until recently I had never interacted with him. 
Everyone remembers that thread. I won't bring up. Well, I spoke my mind and it was not very nice. SL and I did some back and forthing...
It ended up that we were both working on a project, that shall remain nameless. He was the only person that I could really contact  about the project and my part needed to be done. So I had to put on my big girl panties and act like a mature adult with this guy I had so many misconceptions about.
So, I contacted SL, with an open mind and we got the job done. 
This was not hobby related. There was no BCD. But SL and I sat, like two unlikely people and got to know one another. I believe we both enjoyed each other's company. 

 No bcd, just hanging out. 
That was a couple of months ago! 
Don't Believe Everything You See & Hear People!! Take the time to get to know people. Keep an open mind. 
Merry Christmas to one hell of a generous guy!
