The crux of that argument was that the OP was too stupid to do the work himself, and that's why he shouldn't port a cylinder head. I say... "who cares?". Are we playing God here on who is good enough to do this work,
I hate it when "experts" don't let others make mistakes. It is so awfully selfish.
I'll call you out here mate, it really sh1ts me when someone interprets others concerns as calling the OP stupid, NO ONE said that what so ever, no one even insinuated that , nice way to twist a subject to suit your little rant...

No one was "playing God " either, personally for me, there is NO God so that kinda screws that bit up as well. You see, the more experienced members here have been doing things for a hell of a lot longer than say, YOU maybe, {see how that works} your post sounded very immature so i'll "assume" that you are younger and maybe less experienced...? {starting to dislike assumptions yet?} Do you know how easy it is to actually screw up a head...? Do you own or have you ever owned the correct tools used for porting..? One can destroy a head in minutes without the knowledge to even start porting, its an art in itself. If I were completely inexperienced at this I would seek out someone with the skills needed and pick their brains, when you join a PUBLIC forum that happens naturally. What most commentators in that thread were trying to get across is that "mistakes" can be expensive, sure, anyone can hand sand a port and clean it up {thats not porting}, but when it comes to properly porting a head you must posses some knowledge as to what you are doing and what you are trying to achieve. If you have 5-10 heads laying around, then by all means, port away until you get it right, {how would you even know what right...?} if you can't afford that then ask questions as the OP in that thread did. If you get upset by others opinions and people trying to help, and pointing out what could possibly happen, maybe your in the wrong place. That was an extremely poorly worded rant Camelman....

And for what its worth, I know people that shouldn't be allowed to use a bloody screw driver, let alone a porting tool, and they aren't stupid at all, they just posses different skill sets, I've seen plenty of people like that here in the last ten years, thats probably why they come here for HELP....
