“I grew up eating peanuts on Pesach, and I clearly remember my Mom z”l using peanut oil. You cannot convince me that some time between the late 60s/early 70s until today that peanuts magically became kitniyot.”
Me neither. However, I can be convinced that most poskim hold that peanuts were always considered (or at least, should always have been considered) kitniyos.

Just because a grain has been (relatively) recently discovered does not mean that it can’t fall into a category, and hence a prohibition, that is hundreds of years older. And it is nothing short of ridiculous to say that finding another application of a rule is changing the essence of the rule; would you say the fact that turning on a light is assur shows that Shabbos observance can be “changed”?!

“As to Quinoa, the Star-K tested and researched it and proved that Quinoa is not kitniyos and as you say, the issue has gone wild and taken on a life of it’s own. That’s the times we live in. The Chumrah of the month club run amok.”
While there are indeed qualified poskim who are matir quinoa, I’m under the impression that there are qualified poskim who assur it as well. Just because somebody holds a different halachic position than you do is no reason to belittle it.

“I’ve mentioned this before but no one has ever responded. If minhagim cannot change, how were the chassidim able to throw away centuries of minhagim? They discarded the nusach and adopted a new one.”
First of all, they adopted a nusach in line with teachings of the Ari, not just their stomachs. Second, many were indeed very upset at them.
