When all of the scientist agree, get back to me. Evidently you do not know that basic law of genetics---Genes determine the characteristics the offspring will have. Characteristics in the offspring can only come from the genes in the gene pool of it s parents.
Is that true of false? If you say "false", explain where the characteristics come from
Of course that's false. What genes direct the production of fetal alcohol syndrome? None It's acquired in utero.
How about the microcephaly caused by Zika? Where is the microcephaly gene in the gene pool?
Toxins, infections, strangulation of the fetus by the cord, poisons, radiation - they can all potentially contribute to the characteristics of the offspring absent genetic mechanisms. How is it that you are unaware of that, but keep citing the laws of genetics as if you have authoritative scientific knowledge about the topic?
Mistakes like these tend to undermine your implied claim of authoritative knowledge.
I learned an interesting and helpful concept while studying argumentation that you might benefit from. It's called ethos, and refers to how the source is perceived apart from his message itself:
"In the study of argumentation, ethos refers to how the writer or speaker is perceived by his audience. It's a combination of perceptions such as, Is he knowledgeable about that which speaks? Is he fair? Does he have any unstated purpose? Is he polite? Can he be trusted? - in short, his character, credibility, and motivations. This is all separate from the argument or message itself (logos)."
You want to protect that.
