I dont know if you're a dick...you've seemed pretty decent to me on here and at the track.
However, I think people who ride track days get upset or offended about a couple of things...
1) If you offer up "I got bumped". No matter how you intend it or whatever context it is mentioned people seem to take it as bragging. This of course is after you thank the CR who helped you and bumped you.
2) If you comment on how slow a person or group is. Kinda like #1, if they are slow you must be fast...people assume you are bragging as well as condescending. I'm not saying any of your comments were this way. This is just my observation.
3) comparing different orgs. People who are regulars with NESBA are typically loyal to NESBA. People who are regulars with STT or TPM or Elite or whoever else, are typically loyal to those groups. People have their own reasons for riding with the group they ride with. So they dont want you to come on the STT board and say their group is slow or anything else negative. Just like most of NESBA bows up when someone says something negative about us.
4) the forums are great for communicating and catching up with friends who ride or talking with new friends we meet at the track. But on the forum, you cannot see someones face or hear their inflection when they say something. You don't get the full meaning if you don't hear their tone. So while your comments were probably intended innocently enough and you were most likely trying to offer some constructive criticism, people miss the meaning by reading the words.
My opinion is,
group is not
group everywhere you go. So if you choose to ride with other groups you have to deal with it. As for the speed differential in places like the back straight at RA and the early braking entering 12...that's part of riding on the track. It shouldn't hold you up if someone is slow on a straight and if they brake way early entering 12, you have another long straight followed by an uphill high-speed sweeper. You should be able to get around without incident and they should be able to learn and ride at their own pace.
