Gakkuai's school-uniform lesson on strong and weak reasons

A post describes a Gakkuai lesson in which kids choose three of five reasons supporting the opinion that school uniforms are good. It says “School uniforms are cool” and “I don't like picking out clothes in the morning” are marked weak. Raku, a character in the app, explains that the latter reason matters to only one person. The poster likes that kids choose before seeing the explanation.
