Rose McGowan blasted Caitlyn Jenner for her light-hearted remarks that the “hardest part about being a woman is figuring out what to wear” during Jenner’s acceptance speech at the Glamour Women of the Year Awards.

The actress and director wrote a fiery reply to the comments on her Facebook page.

“Caitlyn Jenner you do not understand what being a woman is about at all,” McGowan wrote. “You want to be a woman and stand with us — well learn us. We are more than deciding what to wear.”

McGowan went on to write “You’re a woman now? Well f—king learn that we have had a VERY different experience than your life of male privilege. Woman of the year? No, not until you wake up and join the fight. “

Later, McGowan expanded on her previous commentary.

“Let me amend this by saying I’m happy for what she’s doing visibility wise for the trans community, and I’m happy she’s living her truth,” McGowan wrote. “If you know you are going to be speaking to media about being a woman, maybe come to understand our struggles.

McGowan’s Facebook post has since been deleted.
