Some countries or state have been accepting this kind of marriage. Here in the Philippines, we do not recognize it as legal or something like that. How about in your country?
In Philippines the political influence of catholic church was built throughout our history where priest runs the community, their voice is very powerful and we raised from the word of God that they believe in. So as for controversial issues like this religious groups opposing it directly and politicians are afraid to take a stand against it because they know the influence of church in our society. But if we look at Latin America they are some country that legalized same sex marriage like Argentina, Brazil and Colombia we all know that majority of Latin America were Catholic. While Islamic region also opposed on this matter. As a believer I'm not infavor in same sex marriage but it doesn't mean that I'm against on LGBT's rights, I also have a close friend that belong to LGBT and I respected her/him. Kindly respect my opinion.
I don't know Lucario. Why would you refuse your friend the opportunity to build a happy family and adopt a chils. I'm not sure that he/she's really your friend. He/she's like a doll for you. And that's that the problem. The LGBT people are not dolls. They are just people with un-orthodox sexual orientation that want to make families and adopt children. Stop treating your friend as a doll, I guess. That's a human being, we are talking about. I'm not sure that we have several lives. So, that human being is goind to die in several years or decades and... that's it. He/she's just going to stop existing. There's no haven/devil, there's no God, there's no nothing. It's like when you iPhone dies. It's just gone. Accept this truth...
So, we need to be happy and really try to let others be happy as well. You, I, he/she are going to die in a couple of decades. And there will no afterlife after the death. That's why, it's so important to get a family and get a child. You won't get a second child.
If we can store conscience in the clouds, it's gonna chance everything. The minute we do that, we'll lose the gender and other physical stuff. But we are not there yet.
