I think you're overthinking this. This is a forum for hobbyists not experts. Everybody has an opinion, many of them are strongly held, but very few of them are the one correct way for doing something. There are usually multiple paths to success though some paths lead to greater successes then others.

People who have had a success doing something a certain way will often advise others to follow their process, people who have had success doing the same thing using a different path will often give examples of their process and examples of their successes. Both may defend their process as being the 'correct' way even though both of them have been successful. This doesn't mean they are 'attacking' each other, it simply means that they are in disagreement.

I personally think that disagreement is a GOOD thing as long as it remains civil and free of threats. Differing opinions give the other people reading the posts options to try for themselves. People do not become good keepers by being led by the hand and told exactly what to do, people become good keepers by being given options to try for themselves so that they can discover what works best for them. Remember that this forum medium is not really a two way conversation. Even though there may only be a few people responding to a post, there may be many hundereds that are reading it.

My oldest son also has Aspergers, he often has trouble differentiating the difference between people disagreeing with him and people being mean to him. I'm not saying that this is your issue, but being confused by social cues is also something that comes with Aspergers.
