I don't see a factual gap between the points
The issue that provoked the 'foul attitude' wasn't the factual point (though it is wrong, and I would have been able to explain better why it was wrong had I not been distracted by the attitude of the post), but the superior and dismissive attitude of "Also those mentioning Amersham to London are forgetting <the irrelevant non sequitur of Chiltern trains>" that left a very foul taste in my mouth that I couldn't swallow and had to spit out.
Only I had mentioned Amersham - so why not mention me by name, or quote my post, or actually engage with what I said? Because this wasn't about the points I had made - other than to sweepingly rule them irrelevant them by ad hominem. It was an attack on me, on an irrelevant point, so as to be able to declare my inferiority and dismiss my points without engaging with them.
I hadn't forgotten Chiltern, just didn't feel the need to mention these trains that I use often and hear most nights - because it was totally and utterly irrelevant to the points being discussed.
I do note that there wasn't any mention from you of Chiltern until it was pointed out.
Given it was only brought up as a non sequitur to poison the well, why would I have brought up this irrelevant thing?
Even without GWR provides a similar service to Maidenhead (which I had mentioned at that point, because you didn't know it existed) that is even better in the peak than Chiltern's offering to Amersham vs the Met's, it's totally irrelevant as the journey I mentioned (Amersham-KXSP) is a journey where people will use the Met, not Chiltern.
What's the point of discussion if you label someone you don't know as disgustingly arrogant in that circumstance?
What's the point of discussion if, instead of discussing the points you've made, you get smeared as ignorant in order to avoid discussing the points you've made?
Hold on! The Mayor and/or TfL may have insisted on expanding to outside Greater London but London Council Tax payers have not!
I'm sure the London Council Taxpayers would very much enjoy the additional fare revenue from those places outside London that will bring in more than having the services head that far west costs...
