Their scripture is still full of outright, undeniable racism, and they consider the Book of Mormon to be the word of God. That's all the proof I need. They may have eased back on public racism, but for them to disavow their religion's racism would be to disavow their church entirely.
Mormon men may be taught to respect women, but women are taught that they should more-or-less stay at home and make babies, and for most of the community, if a women gets past her early twenties and isn't a housewife, it's seen as a failure. I consider that sexism.
