So first off let me just say i am certainly not supporting incestious relationships, but those saying “well incest has genetic problems and there are no problems with gay relationships for children” is absolutely disingenuous. Gay men are the largest group with several stds. Despite being maybe a 1% of the population they account for 70% of all AIDS cases in the US and 83% of all syphilis cases as well, just to name two. https://www.cdc.gov/hiv/group/msm/index.html https://www.cdc.gov/msmhealth/STD.htm These diseases then spread even more through surrogate adoption and parenting which not only infects the children but also the surrogate. Anal is naturally risky for obvious reasons and even in straight couples who have tried anal their rate of stds is high, although not as high as the gay community. So both have potential lasting repercussions for children and saying that only incestous relationships will have harmful effects is completely ignoring the problems in the gay community. [spoiler]And now i will probably be called homophobic for daring to bring any of this up. [/spoiler]
