Let's just go there. This is what we, and even our grade school kids and grandkids, at their formative stages of life, and our older kids in their sexually active stages of life, are being encouraged to happily support and accept.
http://factsaboutyouth.com/posts/physical-health/Liberals will NOT have discussions about this, typically. What they don't get is that Christians who practice their faith, and anyone else with a functioning sense of reason, accept the person, but not the behavior. Loving someone doesn't mean wanting to promote and normalize whatever they are doing.
Tons of actual research out there shows the shadow side of gay marriage ... it's pretty bleak for men, and horrendously damaging for any kids they are raising.
With all its own struggles, a family based on a heterosexual couple parenting is far and away healthier for everyone. But you won't see the stats on that in the general media, because the truth of it is "hateful" towards gays.
Nope. Love the person, reject the behavior. It's not race, religion, skin color, ethic surname, blah blah blah. It's behavior. And that is COMPLETELY within my rights to reject and refuse to support and encourage.
