Same sex marriages don’t affect the people around them because it is not physically or mentally changing their state of being. It is just another thing that religion wants to argue about because it is not a part of the religious custom. The religious figures need to adapt to the new customs for society; with adapting to the new ways, society will become stronger through the addition of diversity.
In my opinion, love is love even when two people of the same sex get married. It should be recognized no matter the form or principle of a situation.
