We can easily find arguments that speak the language of the culture clearly. Principles of
diversity and equality have been perverted and we need to correct our culture and get the
true meanings back.
For example you could ask anyone the following simple sequence of
questions:
1. How much gender diversity is in all same-sex unions? (hint: Zero)
2. Is gender diversity good? (hint: yes)
3. How much gender diversity does a marriage of one man and one
woman have? (hint: 100%)
One man, one woman was an invention of creation containing diversity
and equal treatment of genders since the beginning of time with Adam and Eve... Two
diverse gender working together in harmony as one. However, men have messed things up
along the way by abusing women (and vice-versa). Genders were created to be complementary.
Both sexes are uniquely qualified and absolutely necessary for a baby to be born. There is
not one person in civilization that exists without one man and one woman.
Thus, marriage can be said to be the oldest equal rights
institution in history.
Both diverse genders are equally represented in traditional
marriage. They have different roles and responsibilities and equal standing before law.
This creates a synergistic, and inclusive, balanced environment for a child to grow in.
Both genders also get equal civil marriage benefits from the government.
In contrast, same-sex marriage denies and excludes the diversity of
both genders by same-sex orientation and then uses the complimentary gender in a parasitic
way as a subservient, second-class womb/sperm-donor or concubine perverting nature's
intended purpose which they originally denied.
Here is a further example. In a male-dominated same-sex 'family',
the government rewards the two unproductive men with tax-payer benefits, even though one
of the men can't have any genetic connection to a child, while the genetic woman who
actually bore the child gets nothing!
Where is the diversity and equal treatment in this?!
You need to continually bring these types of arguments up
to people in order to enlighten our lost and ignorant liberal culture.
