I have had people being offended because someone commented on their own handiwork of wiring a plug and they show it to me and say "Whats wrong with that?"...

Usually/commonly. For years it has been a requirement that electrical items sold in the UK which have a 'power lead' must come with a fitted plug, but, although the p[lug is most often 'molded', that is not necessarily the case.All these frightening examples are the very reason why appliances are now fitted with molded plugs.

Found it.I've got a kettle lead somewhere from a kettle of a customer.
I looked for it earlier but can't find it. When I do, I'll post pictures here.
It belonged to an elderly lady I visited. Let's just say it was a total death trap and every possible thing that could be wrong and every possible hazard that could be present was present.
It was, quite literally, shocking.
The thing predated moulded plugs and the plug was fitted by the husband, who had since died.
I took the kettle and the lead off her and went out and bought her a brand new kettle out of my own pocket.
I've since used the lead as a teaching aid several times.

Can/could you be sure that it wasn't ?And this was done by the elderly lady's husband. You'd think his mission was to do away with her!

I have to say that I've always been a little uncomfortable about 'molded plugs', because they require total blind faith in the process (presumably often/usually an 'automated' one) that terminated the cable into them.
The last one I cut open the conductors were welded to the terminals.It would be interesting one day, to see just how they are terminated, within the moulding.

Same here, and I've taken several apart in my time.The last one I cut open the conductors were welded to the terminals.
