From the DM article:
Aberystwyth SU said: 'Including "Drag socials" as an example of a banned theme is because they are usually about members of random groups dressing up as the opposite gender in a general way that has the intention of being as funny as possible and not as a celebration of LGBTQ+ pride or sexual liberation in the same way that drag is.
'If a society or club wanted to organise a drag social to celebrate drag and LGBT pride then the SU would be supportive of that and would put students in touch with relevant people who could help make that event a success.
Coping with such extreme double-think must surely interfere with your studies.
