Now that is a point I can get behind of. We might not say it outloud, but yes, we do believe every form of speech we can't understand to be gibberish. Still doesn't justify the other affirmatives, like saying "most of the civilized world speaks English", which is downright not true, since, again, most of the civilized world (meaning not tribal natives that don't have any contact with technology at all - and good luck finding some that fit this nowadays, thought there still are), in fact, speaks mandarim.
The guy who was speaking in tongues there (don't recognize the language, so won't even try to guess it so as to not offend anyone), as it seems, said some offensive things, and that is WRONG no matter in WHAT language he said it. On the other hand, the player who posted the complaint was the one who ticked him off, by trying to force him to "play faster" because HE didn't have time to finish the match otherwise, so until FURTHER evidence of this behavior from the foul-mouthed player is presented, I'd be against punishing him for this episode alone.
And yes, I'm completely against every single "players should write in english" comment.
The fact that I'm posting this in English is not proof that everyone can, and in no way limits someone from playing on Gemp (like I said, he can be taught by a player who DOES, in fact, speak English, and play on visual recognition alone from them on, #$&*@!, I could probably still name every card and effect from Fellowship Block with just a glimpse at the picture, and would probably get 90% (or more) correct.
So THIS part, the "everyone should write in English while playing on Gemp" argument, I can't back. And I'm completely against it. Can you imagine if I was playing against, say, Pepin the Breve, WHY ON EARTH should we be writing in anything OTHER than portuguese? So lookers could understand? Makes no sense at all. And yes, this is an extrapolation, but if both him and me CAN play on Gemp, and CAN understand the cards, that doesn't mean we are confortable writing in English, so since Gemp does not require instructions to be given, like GCCG does, I see no reason why anyone should be forced to write in a language they don't want to.
PS: Of course, there's always the alternative for the complaining player, like, say, learning a few more languages instead of just one?
