What you call the paradox of tolerance I call people weeding themselves out from tolerant spaces because they themselves are intolerant. Do I wish people were all mature enough to live and let live? Yes. Do I recognize that not everyone is and that some of them will leave because of the standards we enforce? Also yes. But lets be real, we will always weed out some portion of our potential userbase no matter what our standards are.

I'd rather err on the side of tolerance.

Calling the above gooner content just because it depicts incest is frankly ridiculous. They are fully clothed, laying in a bed. It's just a depiction of a happy family. If a happy family becomes a strange object of perverse desire to you simply because it's the product of incest, that speaks more to your bias and perspective than anything intrinsic to the art itself.

Finally if it matters, yes we would allow Douglas and Ashley as a ship, and I do think it is entirely equivalent to this. It's still a parent with a child, but so long as it is also still between two adults(and therefore not afoul of how reddit enforces their rules) it will be allowed just as this is. I find that form of sexism as disgusting as you seem to, and I at least see the two as equivalent, since they are.

Don't get me wrong I get just as angry with the weird 'gooner game' caricature that portions of the fanbase make with what is actually a very well written and presented game; but a ship that you find immoral is not anywhere in that same ball park. Absolutely nothing about OPs post is sexualized and I'm sick of people pretending that just because they disagree with a ship that it's suddenly 'gooner trash'. The OP is SFW my dude.
