Yes Colin, they are assumptions based upon the information available to me. That is, I am afraid, the way it is in cyberspace.
You seem to think this is a "real" world, hence your comparison to a pub or the workplace.
Whilst certain human traits always surface, this bears no comparison to the real world.
People can say what ever they like on here, spend hours sourcing information on the net to appear more well informed than others.
I come onto these chat rooms without any desire to want to be liked by the people on them, nor do I come on here to try to "get in with the in crowd". I have a life outside of my interest in racing/betting and have no desire to create a virtual life on here - this is a forum, I post my opinion and thats it.
Sorry if that disappoints you.
