There are a couple issues with extended threads in a language other than English.
First the forum rules state:"Post in the language of the forum". EA's forum, EA's rules
I never mind if a question is posted in another language and a quick answer given. I can even live with an answer given in the other language with the English translation
Extended other language threads are rude. It has nothing to do with exclusion or any other politics. It's just rude. Google translate works both ways. When I go somewhere that the language is different I do everything I can to communicate in their language.
Many people who post here in another language are unaware this is an English forum, and most try to communicate the best they can.
My big question is... Why is this such an issue? We are here to share and help each other. Be safe, be kind, be caring.
