I think that the this forum should be open to everyone, and it should be a place where NTs can feel welcome and seek relationship advice if they need to.
Some NTs come with good intentions and approach the matter with sensitivity, and a genuine desire to improve their relationship with their ASD partner by seeking advice and trying to understand ASD better. I have no problem with this, and welcome such people.
Some NTs even go further, by posting in other threads and joining in the discussion, and as long as they do so in a sensitive, non-judgemental manner, they are most welcome as far as I'm concerned. In fact, I wish more of them would, as many can really help us by explaining things from their perspective, making valuable contributions.
However, there is another kind of poster, what 'hit and run' kind of poster, the One Post Wonder - they come and make a thread after a break-up, which is usually a rant about all the failings of their ND partner, why doesn't he show affection, why doesn't he ever tell me he loves me, why doesn't he do this or do that, etc etc... you know the kind I mean. Often people spend a lot of time writing thoughtful replies with good, honest advice, but you never hear from the OP again... or there's the other kind, who will dispute everything you say, or expect you to somehow miraculously solve their problems for you, which you can't - these people are anonymous strangers on the internet... I don't know them, relationships are complex and it would just not be possible to convey the complete dynamics of their relationship on an internet forum or for me to fully understand it, so how can I advise? How can I possibly know whether they are compatible or not, whether they should break up, whether the ASD partner shoudl get tested, etc? What can I say? I rarely reply to these threads, because I don't know what to say, they need communicate to work in out themselves, or in the case of a break-up, they need to move on.
Very often it's not the fact that they are having difficulties understanding their ASD partner that's the main issue, it's the tone or language they use, and the insensitivity... some come across as a huge, long rant, or a long list of complaints and flaws. They need to remember the context of the forum - it's main purpose is a support forum for people with ASD, so they need to think a bit more about how the content of their posts might come acrosss to people with ASD, and express themselves with sensitivity in a non-judgemental way. Edit: if I were to visit an NT forum and rant and complain about my NT partner, I can probably expect a much more hostile reception there than any replies given here.
Another thing that strikes me is this: NTs have in this forum a huge resource at their disposal, information on ASD, a dating and relationships forum with numerous thread about NT/ASD relationships... if they want advice and questions answers, if they really do want to learn about ASD, then why don't they read the forums first? Do some research? Read the advice given to others with similar issues? Read this thread, with the thoughts and reactions to others who post about relationships. Get a feel for how people with ASD think and might react, before making their own thread. The impression I get is that most of them barely do any research, don't read around the forum to get a feel for it.
