No one is creeping on children by posting something. You weren't concerned about the feelings of the dead people, you were concerned about necrophiles being hurt or insulted. People with a sexual attraction to children might come here and be made to feel even worse about themselves when they read stuff like that. like you said, it is fine to be disturbed because of that but keep it to yourself like you recommended. It doesn't contribute to the discussion or the supposed supportive environment of this forum.
Your second point I agreed with entirely. I was just referring to the first. Learning to accept and love yourself is important but that should only be the case if it is clear that your sexual attractions are a part of who you are and were determined before birth or if they don't give you any distress. Still not everyone is ready to accept it. YouthRightsRadical himself has said that accepting himself took quite a while. If this is something that developed later in life and causes you distress, then there are probably emotional or psychological causes for your attractions and they should be identified and worked through. Saying simply accept it and don't worry about it isn't a helpful thing to say at this early stage when none of us have any information and the user is clearly in distress over their attractions.
