You seem to be ignoring my statement that I am not taking sides on this, Big_Bap.
I am telling you that you are going about this all wrong.

You made a thread titled "A question from North American player". It's too vague so you have fewer players opening that thread to start with.
Your OP text said "There is an EN forum thread that talks about deleting FC with less than 4 members. According to data, JP players favor small sized FC. Why does it seem like JP players favor small FCs?"
So you only get players who favor small FCs to write why they like small FCs.
On top of that, you only let the thread be up less than 24 hours to come to a conclusion and say "Nobody agrees with him".

You're not interested in the JP opinion, only in shaping it to back up your argument.

BTW, I am not saying that JP players do not favor small FCs. They do.
But the way you presented them with the question, and the way you used their answers to back your argument is somewhat deceiving.
