Now before you're thinking of ewww disgusting etc. Don't you think you should be able to choose who you want to be with?
Years ago interracial marriage was considert as Not acceptable. It became acceptable
Then it was the gay community, They're widely accept today, Though ofcourse not everywhere but it is going towards the good way for the gay people.
When we all want fairness and equality why shouldn't it be accepted to marry your brother or your sister?
Is it really fair to be told no you can't marry your sibling because "we" the goverment won't allow it?
And then there is the whole sick children issue, If everyone who is carrying the most lethal desease or someone with very bad genetics is accepted to have children why should this be an issue for people who want to participate in incest?
Don't get me wrong though i'm not actually interessted in having a relationship with someone in my family, I just find it strange why this is so unacceptable.
Should it really bother other people who you want to marry, wether thats a man or a woman or your brother and sister?
And if the children factor is such a big deal to people personally, What about gay incest where its just not possible, Would that be ok?
