It's always left vague because it would sound horrible if you actually laid out what "Trans Rights" are.
It's rolling back women's rights (their safe spaces, support groups, initiatives, sport segregation, sexual preference and identity) and giving those rights to men in women's clothing.
They want men in women's bathrooms, prisons, support groups, rape shelters, and generally any other place that men clearly do not belong. They want men to replace real women's voices on all levels - from private corporations to all levels of government. The want to shame gay women into having sex with men (it isn't a penis, it's a girldick).
