Yes, I was.

I had my own section, "Marty's Roadhouse."

I quit early on because of the acrimony. If I left an opinion on something, some moron came back at it with insults.
Some guy named Jo emailed me after a couple of months and said that people agreed with me on a lot of stuff and wanted me to come back.
Unsuspecting...I did.
I went back and commented on some guy singing slightly off key, and a tragically troubled personality was allowed to slam me for pages with no moderation.
I still have the unhinged diatribe saved in my files.
You appear a kindred spirit to that personality.
I complained and was given the silly excuse of "free speech."
Same pattern as here.

So I decided to test their rules and have fun with it. I handed back all of the "free speech" that they could handle.
Ultimately, they banned me. Which I was fine with.
Shortly later, the site was gone altogether. With that management style, no surprise there. Their biggest draw was arguments.

What I did NOT do,
I did not level middle school insults at people like a troll such as yourself.
I handed people a look at their disconnected thinking in new light.
I had one guy tell me my insults were "beyond the pale."
I responded by saying that I had been argumentative but kept my punches above the belt.
I asked him to quote me these horrible insults and he couldn't find even one to quote.
These days I'm not as inclined to GAF.

Here are other facts:
I argue nowhere but here and in the past at TS.
You've been to my YouTube page and no doubt to my FB. No political content. No arguments. Smudge the cat shows up regular.
And TS was a decade ago.
You. otoh, take your silly crap about cliques and hostility and talentless people and idiots wherever you go....to this day.
I don't.

And if Brian did not let trolls antagonize me and others, because "all is lost" if he doesn't...I would not be arguing here with a troll like you.
Like the other site...you'd be gone and I would be leaving pleasant comments about songs.

(Jimmy Kimmel and many others woke up out of a job this morning due to adolescent and misguided notions of what the 2nd amendment is actual intended for.)

SO THERE IS YOUR ANSWER....

Now, Answer my questions, troll...

Answer the very simple questions.
When that hostility formed;

Did you call people "talentless?"
Did you call people "idiots?"
Did you call people other various demeaning names?
