I have stated many times, "I do not like it."

And, if you want to see other places in the fandom that have banned it, check out Eurofurence, which is governed by the same laws as Xenofur is. Their lawyers are more knowledgeable about German law than any of us are. Then check Further Confusion, who also banned it. Their lawyers have explored this issue thoroughly and made that decision based on current legal interpretation. Also, check FurBid, one of the first places in the fandom to ban underage art, who also had lawyers investigate all options.

Just because Fur Affinity did not ban it is no reason to assume it is acceptable. If we followed that logic, Centaurs would still be un-furry, because Yerf declared them such.

The full truth is, laws do exist, on both state and federal levels. Some of them have been challenged, and failed. Some have not been challenged yet. In one case, one was challenged, they won, then it was re-challenged and lost, and now it is on the docket for the Supreme Court, and we have no answer yet as they have not made a decision.
We, as fchan, and your furry fandom do not wish to be the first test of the law. We do not like the stuff, we do not want it here, and frankly, we have  far better uses for our time and money than fighting a legal defense for something we do not like. Like, chocolate, movies, and long pointless walks on the beach at sunset.
Unless they were with a very cute girl.
