Yes, Violet, OP is conflating homosexuality with not reproducing. Which ignores that a) lots of lesbians & gay men do have children, and always have done so; and b) lots of other people who weren't/aren't homosexual through human history have not reproduced for a wide variety of reasons - infertility, poor health & disability, early death, choice/preference, never got the chance, no interest in sex & coupling up, dislike of children, tokophobia (a real problem for women that is quite understandable under any circumstances, but especially when there was/is high rates of maternal mortality in/after childbirth), membership in religious orders that require swearing off sexual partnerships, marriage & family life... and so on.

Moreover, OP seems to think that everyone who experiences "same-sex attraction" is homosexual, which is certainly not the case.

Finally, OP seems to think that most human beings who walk the earth are the result of consensual coitus between males & females engaged in romantic pair bonding. When, in fact, many of the earth's human inhabitants historically were & still are the result of rape in and outside marriage - including child rape by fathers, brothers & uncles - as well as of forced & arranged marriages & other coercive, abusive situations in which the sexual attraction & orientation of the girls & women who became/become pregnant did not factor in at all.

In warfare, mass rape & impregnation of girls & women has been commonly employed (as happened in Nanjing China when the Imperial Japanese invaded in WW2, in Bosnia in the 1990s, & in Germany when the Soviet forces headed to Berlin in the spring of 1945). But even in situations that are far less violent, the fact remains that many girls & women become pregnant in the context of relationships that they did not enter or stay in by choice and in which they have little agency or say, and their own sexual attractions, urges & orientations are not factors in what sex acts they engage in or determinants of whether they become mothers.

Seems the historical fiction shows and films OP spends time watching don't include the likes of Tess of the d'Ubervilles, Eastern Promises, Rob Roy, Lost in Bejing, The Color Purple, The Magdalene Sisters, Sin and Redemption and many, many more.
