Might be a fake story, but it is entertaining.
Even if it is a silly story, it actually is quite reflective of some people's political perspective. As in, they will consider gay marriage to be THE litmus test for what they call freedom.
"If gay people can marry, then you have freedom! Never mind all the other obtrusive laws that actually restrict freedom, homosexuality is the only thing that matters! So who cares if you can get arrest for hate speech, gay marriage!"
So when you are forcing others to accept something at the point of a gun, you are not pro-freedom in the slightest. Even if in your mind having gay marriage be legalized is one aspect of freedom, we are not doing goodwill in the world by telling the world they need to tow the line with more "tolerance." As mentioned previously, it does not end simply at letting gay people marry. The slippery slope is no fallacy, but rather a reality. More will be demanded.
And I have not even touched on how this madness is being done at the expense of our own wellbeing. Like the characters in the story, we are seeing a lot of effort and resources being put in place to push progressive values worldwide, including gay marriage. Are we really willing to put ourselves on the brink of collapse in the name of equality? Not necessarily, but those who are in charge appear to be. So we go further into collapse trying to push for values that won't be there once things break
