First it is not a good reason not to know the rules of something you are joining, that's a bad habit.
Secondly you can tell them nicely or ask them what they are trying to say just to avoid them from being insulted, Creating International and Filipino sections is a good idea if we are like a thousand members, but think of it this way, you gave the percentage, 75% are filipino, it means if we create those sections, there is a very big possibility that filipino section will be visited more regularly and English will somewhat be ignored.
There is nothing wrong with telling someone or asking them what they are trying to say as long as you say them nicely.
