This video is not exactly accurate and goes after Christians by naming the guy “Christian.” A tendency to be left handed is very clearly more genetic than a tendency to be gay, and a tendency to be religious might even be more genetic than a tendency to be gay.
These people didn’t need to exaggerate and go on the offensive. When the left says things which are exaggerations and attacks the right, it is not less wrong than when the right exaggerates and attacks the left

What Twins Reveal About The Science Of Faith
Biology and sexual orientation - Wikipedia
“
A 2010 study of all adult twins in Sweden (more than 7,600 twins)
[11] found that same-sex behavior was explained by both heritable factors and individual-specific environmental sources (such as prenatal environment, experience with illness and trauma, as well as peer groups, and sexual experiences), while influences of shared-environment variables such as familial environment and social attitudes had a weaker, but significant effect. Women showed a statistically non-significant trend to weaker influence of hereditary effects, while men showed no effect of shared environmental effects. The use of all adult twins in Sweden was designed to address the criticism of volunteer studies, in which a potential bias towards participation by gay twins may influence the results;
Biometric modeling revealed that, in men, genetic effects explained .34–.39 of the variance [of sexual orientation], the shared environment .00, and the individual-specific environment .61–.66 of the variance. Corresponding estimates among women were .18–.19 for genetic factors, .16–.17 for shared environmental, and .64–.66 for unique environmental factors. Although wide confidence intervals suggest cautious interpretation, the results are consistent with moderate, primarily genetic, familial effects, and moderate to large effects of the nonshared environment (social and biological) on same-sex sexual behavior.
