1. Pretty obviously, epigenetics in bacteria provides only very weak support for epigenetics in humans.
2. The case against epigenetics in humans is laid out nicely by Razib Khan: https://www.razibkhan.com/p/you-cant-take-it-with-you-straig...
3. I've been to a few conferences which mixed geneticists with (human) epigenetics guys, and I have never been impressed with the quality of their work. Lots of different measures of "biological clocks". Lots of multiple hypotheses without much correcting for them. No clear theory. I ended up being very skeptical.
I’d be curious to get to the heart of why we believe heritability in behavior is due to genetic changes. It’s way more likely to be due to mimetic changes.
in terse, behaviour is dependent on neural activity; neural activity is dependent on expressivity, and penetrance of genetic constituency.

Throwing out a fundamentals text is valid. But you need to point out where OP made a mistake that's so elementary it requires going back to the basics for it to not come across as low dismissal.
the entire OP displays a lack of knowledge regarding epigenetic mechanisms, as well as a lack ot knowledge base required to make an informed appraisal.
the knowledge base required, is extensive for a non biologist, and made difficult to attain without experience interpreting decades long synthesis.
thus the fundamentals are provided, should anyone desire breadcrumbs pursuant to independant edifiction.
