I, for one, think Hanayo looks better with short hair. It's very cute and has a 30s style air to it.
As for the discussion, while I agree that dismissing Class S feels ignorant, it's equally, if not more ignorant to underplay the importance of "realistic" yuri. It comes off as you viewing the experience of those real Japanese lesbians as inauthentic and the "Western" LGBT+ values they hold as a foregin inveding force. Many lesbian and sapphic mangaka talk about LGBT+ issues and rights and the treatment of lesbianism by Japanese society. Don't throw them under the bus.
