I watched this interview a few days ago.

The gist is that the daughter became indoctrinated around 14 years old by Tumblr/Deviantart - before this time she was very feminine, never presented as masculine. When she was about 17 or 18 she decided to go on testosterone. The mother did a bunch of research and saw that the likelihood of women having heart attacks on testosterone is extremely high, and since they have heart disease running through the family, the likelihood of her having a fatal heart attack before 30 is very high. The daughter said dying before 30 would be worth it to have a beard and a deeper voice. The daughter considers herself a gay man, even though her boyfriend considers himself a straight man.

There wasn't anything hateful in the video. Just a very sad mom who obviously loves her child a lot.
