Quoted from wizard_mode:

Well, here goes. Feel free to offer advice, call me a dumb noob, tell me I am going to kill myself if I do that, etc, etc. Honestly I have heard it all before and have eaten popcorn while watching novices get beraded on pinside and that's just fine. I think some people have knowledge and feel that noone else is entitled to learn. But, even those people were novices at some point in time (back in the 70s maybe?). Atleast that's my take...

WTF? Nobody even said anything. People here are generally helpful especially on actual pinball-relevant repair topics where they don't stray too much off of the path unlike some of those new game discussion posts.

You make it sound like it's a fetish.
