I really don't know what to say to you, if all you're coming away is some resentment at the "evil stingy old people", who shouted you into the ground.
If you haven't noticed, when you posted this topic, there was an almost identical one below it ("Playing in modes"), where people have already explained several times why you cannot just build triads and seventh chords over modes mindlessly* and expect them to remain modes.
* - Contrary to ghettosynth's interpretation, mindlessly here doesn't mean "stupidly", or "while also being stupid", but instead it means "without thought". It means "hey I have these seven notes, so let's see, one triad, two triads, three triads, hey it's working haha".
That, in itself, is an act against all known forum etiquette. Then, when you were called out, you began a psychological game of shifting around and trying to come out of the whole thing looking as good as you can, which, I think, is the pinnacle of trolldom.
BTW, not that it counts for anything, but did you or did you not in the end understand what is wrong with your chords? If you did, then just write the whole exchange here up as "well older people can be aggressive as hell", but since you've learned something new, I'd just let it go in your place.
