just found this out lol - same sex behaviour has been documented in over 1,500 species across various animal groups, including mammals, birds, reptiles, amphibians, fish, and even invertebrates. This includes activities like sexual activity, courtship, affection, pair bonding, and co-parenting.
SV40 hasn't been used since the 60s, and there was no evidence of a definitive link between the contaminated polio vaccines they were used in and an increased risk of cancer in humans, however, if you have some evidence for me that shows a link I would be open minded to it.
Drug relations and testing I believe became much stricter as a result of the effects of thalidomide (in the form of oral medication) which was prevented from being used in the US anyway. Since then, they have found effective ways of using it like treating multiple myeloma (a literal form of cancer!) when combined with dexamethasone, and treating skin lesions of leprosy. It works by reducing inflammation and inhibiting the growth of new blood vessels.
Also for the record I'm not liberal and I don't support Biden.
