This is a common misconception. Red blood cells (erythrocytes) do not contain DNA or RNA, they have no nucleus. In their evolutionary history they jettisoned everything that wasn't necessary to carry oxygen and carbon dioxide. During development they have a nucleus but once they mature and before they enter the circulatory system their nucleus is discarded.

The white blood cells (leukocytes) do have nuclei and hence DNA. This is why blood can be used for forensic DNA profiling.
In this regard scientifically illiterate Melinda is more wrong. It is utterly absurd to propose that the spermatozoa in a vagina after ejaculation somehow, magically, make their way into the circulatory system releasing their DNA into plasma. Even if they were to achieve this miraculous act, erythrocytes carry no DNA that will magically interact with DNA released by the spermatozoa that magically made their way through the vaginal mucosa. Further, erythrocytes have no mechanism for incorporating external DNA into themselves. They have no such cellular machinery.
Of the leukocytes, the phagocytes (neutrophils and monocytes) would destroy any DNA they find in plasma. It would be treated as a foreign body.
Melinda's scientific illiteracy is expressed well in her complete ignorance of relative sizes and permeability of physiological components. A DNA molecule -- let alone the head (and tail? I don't know what her fetid little mind is imagining) -- can't cross the vaginal mucosa in the same way that a loaf of bread can't be pushed into the coin slot of a parking meter.

A cyclosporin A molecule is 1.6nm x 1.24nm and has a molecular weight (MW) of 1203 Da. Further,

So despite the "chameolonic" ability of cyclosporin A it is barely able to traverse vaginal mucosa even when that mucosa has had the protective epithelium removed.
A human DNA molecule is 2 nm wide and stretched it has a length of 2 m. It has a molecular weight of 2.15 x 10^12 Da.
2.15 x 10^12 Da is many orders of magnitude greater than 1203 Da. It is 9 orders of magnitude larger. A DNA molecule has zero chance of crossing vaginal mucosa. Even on the basis of dimensions rather than MW it can't be done, it's wider than a cyclosporin A molecule..
The notion of a spermatozoon traversing the vaginal mucosa is utterly ludicrous. The head of a human spermatozoon is 5100 nm wide. The human vaginal microbiome includes lactobacilli. Lactobacilli are about 700 nm wide. Lactobacilli would be entering the circulatory system via the vaginal mucosa. This would result in septicemia and the sheer volume of bacteria of the vaginal microbiome entering the circulatory system would produce a quick death.
I'm quite confident that Melinda understands none of the above but nevertheless has an idiotic opinion about it because she is an idiot.
@Sir Dank-a-Lot stated something earlier which bears repeating because it gets to the core of one of Melinda's chief behavioral traits but it can be extended further. Melinda isn't just ignorant, she is meta-ignorant. She is ignorant about her ignorance. She is so ignorant she has no comprehension of the breadth and depth of her ignorance. This is the Dunning-Kruger Effect as others have mentioned. But the Dunning-Kruger Effect doesn't fully capture Melinda. In addition to being profoundly and cripplingly ignorant she is also profoundly and cripplingly stupid. She is an imbecile but her delusional disorder of the grandiose subtype (as defined in the DSM-V) causes her to believe she is a genius. She has repeatedly declared herself to be a genius. She has a "Genius level IQ" she tells us (with random capitalisation) yet she has no understanding of what IQ is, nor how it is measured and she has never sat a professionally administered IQ test. Melinda is so stupid that in proclaiming her intellect she demonstrates repeatedly that she is both meta-ignorant and cretinous. She has also described her moral virtue in similar grandiose terms.
The combination of meta-ignorance and delusional disorder (of the grandiose subtype) is an utterly toxic blend of malignant cognitive and psychopathological trait. Every possible means of escape from her abject ignorance, morally reprehensible behaviour and inveterate idiocy is preemptively blocked. The figurative prison is not only invisible but there is a cherished illusion of expansive freedom, supremely rational action and transcendent virtue. If I believed in divine curses this would meet the criteria of a cruel divine curse. It would be an evil deity that inflicts such stupidity and ignorance on someone and at the same time inflicts another layer of personality flaws that assure that a person stays stupid and ignorant.
All accurate. I probably should have been more clear initially but Mel isn't good with small details and exceptions to rules.
