DC has just started school. Another child in the class has two mums, I’ll call them A and B. We have a class rep who volunteered earlier in the term and collected contact numbers for the other class parents for a WhatsApp group, which is mostly the mums but a few dads too. A and B both do the school run, it’s probably A most days but B is there at least once a week. A and B are both in the WhatsApp group and both reply to messages pretty equally. The class rep is organising two social events and posted about them in the WhatsApp group last week. One for the mums and one for the dads. Most of the dads aren’t in the WhatsApp group, so the class rep asked in there for mums to send over contact numbers for their partners or kids dads so that the dads evening could be organised. A few of the kids in DCs class have divorced parents, so I think the idea is so both parents can be involved with other class parents. The class rep has made a separate WhatsApp group for the mums event and her DH has made one for the dads. They put A in the mums group for the mums event and B in the dads group for the dads event.
B asked if this was a mistake in the main WhatsApp group, and the class rep has come back saying that it’s not a mistake, it’s because she and some of the other mums have agreed it wouldn’t be fair for her and A to both come to the mums event. Most of the mums don’t know each other very well, and they want everyone to be in the same boat and mix with each other. They’re saying no bringing your partner to either the mums or the dads event, so A can’t bring B. The class rep has said she’s put A in the mums group and B in the dads group because she thought B would fit in better with the dads than A. A and B have both said they won’t be going.
AIBU to think this is homophobia and let the class teacher know?
