So HL,
Now that you've discovered the other post's origin was not this thread but instead another RC magazine (that the other OP admits wasn't mentioned for
several pages, but was posted long before you've joined our little community), are you willing to retract your accusation?
In my country accusing someone of something wrongly and stirring up trouble with no apology or retraction is "outright WRONG".
Unfortunately it happens regularly, but it's still poor form none the less.
While I understand your righteous anger, I believe it needs to be tempered with reality and grace, since you have found yourself blowing a misunderstanding up to embarrassing proportions.
I believe a retraction here is merited, as is an apology to the other OP (instead of a semantic argument over plan built vs. scratch built). Neither have done you harm but you have acted as such.
You are an adult, and I won't pretend to say I can force you to do what I see is right, but if you expect to retain moral high ground you will need to act as righteously as you demand of others.
