Returning just once to the OT part (sorry) ...
Maybe some of the bad feeling lately is because, even for advanced speakers who usually only make minor mistakes, it's just easier to inadvertently violate one of the Lakoff politeness principles related discussion: to impose - im wissenschaftlichen Zusammenhan...
in a foreign language. And all the more so if it's not
inadvertent, if you really don't pay as much attention as you should to the rules of normal give-and-take.
For example, maybe it feels like an imposition (Lakoff no. 1) when someone says 'Look, you have to do this' (in any language), and it's only exacerbated if they don't seem to give you any room to disagree (Lakoff no. 2) and are not very forthcoming about themselves to establish any friendly basis for interaction (Lakoff no. 3). Given those negatives, if you then make only a minor mistake, it may annoy people more than it otherwise would, and then you may get annoyed and make more mistakes than usual, and it may seem like a further imposition if you then get defensive and ask other people to correct them.

I don't think the best solution is actually to go away and come back with another nick and be even less cooperative, so I hope you won't do that, puertadelsol. You might even be pleasantly surprised if you could just get to know regular forum users like CM2DD a little
better, so that you think of them as real people and are more prepared to be as friendly to them as you would if you were face to face. That's not the same as sharing every detail, but really, native language doesn't seem too much to ask, and it's very helpful to know in a translation forum.
If anyone is interested in discussing that issue further (again), we could start a separate thread.
