@hypolite @Hypolite Petovan What I'm saying is that you don't make arguments, but moralise and judge: "your jokes aren't that funny", "your comparisons show bad taste", "your comments sound privileged" are, at least in my understanding, not arguments, but rather speeches of a priest or a governess. I have no problem with priests and governesses - they are honourable professions - but I am surprised to find them in this discussion, and this after you have accused others of having no arguments. Does that really fit together?

But maybe we have a misunderstanding of language or culture here. Because in the end we come to the same conclusion that alt-texts are helpful even for "funny pictures".

Perhaps I should clarify what an argument is in my sense:just remember that just because a joke loses all its fun to you if it is explained, that does not mean others will all feel the same. We've gotten used to finding descriptions of visual jokes sufficiently amusing;
(copied from the above comment by @Mayana)And here we see clearly what are the advantaged of an argument: it picks up the discussant, addresses his arguments and enables him to change his point of view. Telling him that his jokes are not funny will not achieve that.
