I think you need to calm down a bit isaac, in regards to the heredity thing, but yes I understand what you mean in that there is a vague progressive consensus towards feeling uncomfortable to hostile around non-blank-slateism when it is brought up in relation to people and populations of people
and I'd really wonder what all the people who have parents they cut contact with would think about the very obvious hereditarian conclusion that they are more like their parents than pretty much anyone else
Though interestingly, epigenetics, to my limited knowledge, has demonstrated that there may be a kernel or more of truth to lamarck after all.
Sorry about the delay; I was writing a reply, fell asleep, and tumblr ate it.
I thought I was being calm. The fence around the law keeps getting more fences built around it in the last couple decades.
Epigenetics do provide a scientific explanation for why heredity is not necessary or sufficient to explain traits.
Two people can both be genetically inclined to a trait that certain forms of result in behaviors negative enough that many people would prefer to never speak again with a parent who expresses those behaviors. Eg the child of an alcoholic may themselves be genetically inclined to alcoholism, but also still not want to interact with their alcoholic parent ever again. This is not generally seen as a contradiction. “I will not repeat my parents’ mistakes” is a pretty common sentiment, and isn’t a contradiction. “I know that I am inclined toward a negative tendency because I saw my parents fall into it, so I will take steps to avoid that” is also fairly common.
Epigenetics is a real thing, but it's usually deployed as a meaningless buzzword or just-so story. You can just add "because of epigenetics" to something, without thinking in terms of gene expression or genes to be expressed, and this lets you hand-wave a lot.
