This has always been a can of worms and will continue to be. There is no sense in baiting/name-calling/argueing etc, etc. Nobody is going to change my or anybody else's opinion on a topic by having a go, on the contrary it would probably strengthen our resolve.
We are all proud and passionate about the forum, let's not see it decline.
As to the rules, moderators to moderate and I think Gurus are entitled to lend a hand with supportive/informative posts and nowadays they can hit the REPORT button to highlight probs to moderators. I did this myself before being appointed a mod, I don't like deleting stuff or telling people off, but I like it even less when a thread degenerates to a name-calling session.
As to other old holden stuff, there is a place for most of this on the board. I'd be stuffed with the build-up of my FE if everything was strictly FE/FC. HR Column, Front End and Diff, Torana Brakes, FB/EK Seat surrounds, HK Rims, HZ Motor and Gearbox, LSD diff, electric wiper, DIY wiring kit etc,etc. So people picking their section/topic and post wording carefully can all get along in harmony
Bottom line as I keep saying
Think (read) twice, post once.
Nowadays it's done for you with the preview.
