then the best place to look would be a thread titled "Bus routes in Krakow".
Bus routes, yes; complex social, political or historical issues, no. There should be a little leeway allowed instead of cutting people off at the knees for a little digression. Some mods are notorious for this.
i thought that a forum, based on a particular topic like Poland, would be an accumulation of knowledge
Wikipedia can be useful for that.
Remember it's a fine line between a discussion taking an interesting direction and a discussion returning to various themes that have been done to death in other threads.
I have no problem with what you say. Mods and Admin do, however, have a big problem with a discussion taking any direction other than strictly within the letter of the OP's remit. Boring.
