Why do you think slang is a problem?
I can see down-voting the comment under discussion because it includes a gratuitous insult, but that's a slightly different issue.
Well, I don't know that slang is a problem, but I think it is likely to be one.
This gives me reason to think that using slang is either likely to help people think more rationally, or to cause a slight tendency to think less rationally. Given actually existing correlations, at least those that I perceive, I think the latter more likely than the former.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
