Theland - // Andy, does my opinion constitute preaching?
If so, how? //
It doesn't.
Your opinion is just that - your opinion.
The preaching comes in with the way you present it, or, more accurately, the way you haughtily dismiss naomi for questioning what you say, and asking on multiple occasions for you to point out where you believe she is in error.
Obviously we have never met, but my impression of you is that you would answer questions in the way Michael Foot used to - that little half-laugh as you wind-up your monologue, as though that's the most fatuous question you have ever heard, but you are going to indulge your questioner as though she is a five year old with a personality defect, and you must be patient with the little girly because she knows nothing about anything.
If you address people on here with the respect they deserve as your intellectual equals, you may get some respect in return.
History shows that is unlikely, but hope springs eternal as they say ...
