Why can same-sex marriage be legalized?

Answer 1

If your question is as stated, then I believe same sex marriage can be legalized due to the strong belief in many that love in its purest form should not be bound to a specific sexual preference.

The omnipresent focus on ethical treatment further backs up this proposal, as so many campaigns have been conducted over the years supporting equality.

Many religious followers fail to accept same sex marriage on the basis that past scripture states homosexuality is a sinful act. This said, religion also states adultery is an act punishable to the same extent as homosexuality, however we seem to accept unfaithfulness within relationships in a much more lenient way compared to the marriage of two people who have a genuine love for each other.

In short; if A loves B then let them do whatever regardless of gender/sexual preference.

Answer 2

Same-sex marriage can be legalized because legislatures have the power to define the requirements for marriage and courts have the authority to rule that same-sex couples have a constitutional right to marry.
