It's very interesting seeing the way software communities behave. The BR FreeBSD community is "a little" too aggressive. The international community is more receptive.
It may be and in fact I believe it is related to their maturity and acceptation in the market.
Here both Linux and FreeBSD users are always fighting for more visibility. There are lots of lazy users/admins that always want recipes for their jobs but that find it an abuse of my part if I send them the correct man pages to solve their problem.
In the international community I suppose these people are a little more ashamed they know what they are doing is laziness, but they don't want other people to say how lazy they are and avoid asking such questions.
Of course it happens from time to time, but I really see it in a more restrict way.
It also happens in programming language groups. More frequently when comparing two languages such as Perl and PHP or Python.
In another post (I'm sorry, I don't remember which one, I read it last night and I was really tired) someone said (darobin?) the we should share ideas with such communities, specially the Python one. I agree. But we should preserve our identity.
A programming language is almost a personal taste these days. They solve the same problem with different idioms. Anyway, this is subject for a different post.
