I am myself guilty of sometimes being pissed off by people posting fake cum and similar nonsense as good porn and maybe I have over reacted a few times. But usually the OP of that thread also does not respond in the most friendly way. And considering how readily available non-fake porn is and how known and discussed this is, I find it hard to believe that such people have never come into contact with it and never had a chance to realize that. Especially if those people are English speakers and a part of a large forum like this. So I usually think they are just deliberately ignorant.
I am much less tolerant of abuse though as it is easy to see whether a dog for example does not like something. It is trivially easy to see whether a dog is sexually excited and it is absolutely simple to tell whether a dog has an erection. It may be more tricky with horses for example but when it comes to dogs, the stuff that some people post here is disgusting and they deserve to be confronted harshly.
