This isn't a racism issue, it's a communication one. Back in FFXI I got into a lot of "JP only!" parties because i was willing to use the auto-translate function. It wasn't perfect but it was enough to communicate where we were going to camp, how much tp everyone had, when and in what order we would use weapon skills, and when to magic burst. Since a lot of people just would not use the auto-translate regardless of what language they spoke, it caused a lot of frustration and could kill a multilingual party. With this as a concern, it's easier to advertise that you want the group to all speak the same language. Spend some time with the auto-translate and get used to it, ARR's kind of sucks compared to 11's but it has enough to get basic thoughts through. If you're willing to use it then other people will probably be willing to as well.
