I tried to stay on topic in my initial response by saying simply: She probably doesn't hate you at all.
You may never understand each others' point of view about this particular event... but there are so many more points where you could connect with one another. It would be a shame to label her a "face of hate" just because she disagrees with you about Michfest.
@Jigsaw,
Intersex persons whose genitals are "read" as female, who are raised with girlhoods and an expectation of a future womanhood have had a female-born experience as well. I was going to mention this population, but thought it might seem a little too far off topic ... AND as I am not intersex myself, I hesitate to invoke their experiences in a discussion.
Trans men? I don't believe that very many trans men would want to go to Michfest - so I don't see much purpose in figuring out whether they are included or not, except as a hypothetical exercise, and this topic wasn't about hypotheticals.
The topic is about whether someone who supported Michfest's female-space intention is necessarily a transphobic or hateful person. And my answer is, no, she isn't necessarily a hateful person and it is possible that someone who supports this policy can also be a friend to trans people as well.
