Anyone who reasonably stays within the community guidelines should be treated with respect (respect as in āCourtesyā not necessarily respect as in āadmirationā or looking up to).
Often people come to the forum when they are very frustrated. By nature, this causes their initial communications to be coming primarily from the right hemisphere and be more emotional and disorganized and less logical, analytical, methodical, etc. This should not lead anyone conclude that any such user is a āFoolā or base our entire first impression of their personality or worth on their first post. It would make for a very poor judgment in such a case. I say cut them some slack and give everyone the benefit of the doubt as long as they have stayed within the guidelines. If they have violated any guidelines, alert the mods with a flag so they can handle the situation with the least amount of damage and fallout possible.
After taking a breath and not taking someoneās rant personally, we can often help them to switch more of their communication style away from right hemisphere communication back to left hemisphere communication by avoiding emotionally charged wording, and instead asking them questions that will cause them to have to think and use their left hemisphere more. Politely/courteously ask them many informational questions, questions that require them to be analytical and methodical. This will help them shift toward giving the left hemisphere more executive function control over the current interaction.
Remember, theyāre NOT mad at āyouā and they may normally be very organized and descriptive and methodical and all the things that would be prefered in a first postā¦but often emotion is what prompted people to come here to post when they are quite understandably frustrated. If you can guide them back toward more left hemisphere use, then they will communicate with you more in the way you would like, and in the end more of them will be very grateful for the kind help and understanding.
I suggest we not jump to conclusions about anyone being āfoolsā for any reason, but instead make effort to give people the benefit of doubt, not get offended or reactionary, welcome them to the community, and do our best to help them. Weāll let the mods handle situations that stray outside the community guidelines, and otherwise enjoy each othersā company regardless of what comes up for us in here. 
If you canāt tell, my College degree was primarily psychology and sociology, and Iāve had some training as a therapist.
Ultimately Iāve moved on in a different route that is much more lucrative for meā¦but itās good to have this kind of background for understanding and helping people better.
Anyway, this is my recommendation for how to interact with people who donāt give us all the information we would wish they had given in the first post. Offer understanding and courtesy and request more information. If they donāt give more information then, there isnāt much we can do, but we can always ask, it doesnāt hurt to do so.
