I have never denied that people can change a definition. I do deny that they can change reality. Society now tells us that Jenner is a woman. Hell, they could even pass a law stating that "fact".
Will it change reality? No.
So, you can say gays are married, if it makes you feel better. Reality says something different.

Of course, you're arguing with someone who probably thinks that Bruce Jenner is a woman. Someone who is fawning all over the spectacular new outfit that the Emperor is wearing, and who will call you and I unpardonably stupid or unfit for our posts, for correctly observing that His Majesty is stark naked. May Laurence Tureaud have compassion on him.
I am arguing with delusional people who deny the reality of marraige.
