She was recording the whole silly day because the she went into an area surrounded by people who despise her for existing
The people at the LGBA conference do not despise her for existing
They are strongly opposed to males accessing female spaces and colonising female identity. That was made very clear from the outset, and anyone attending the event did so on the understanding of abiding by those boundaries.
The fact that you think a conference for lesbians to be around other lesbians without male appropriation is a 'silly day' speaks volumes about your homophobia. (As well as raising the question why this person wanted to attend if it was just a 'silly day'. But I think we all know the answer to that.)
