HELP PLSSSS

Can women be misogynistic? My sister is a self-diagnosed incel and it's hella cringy. She insults women and makes fun of them. She also makes those "Women should stay in the kitchen" jokes and expects me to laugh at them. I thought she was just joking at first, but now it has become a daily problem. We can't even converse properly anymore without her being misogynistic and making useless remarks. For example, we were once watching a Tv Show, and a woman on there had a panic attack. Then my sister started saying shit like "Look at that woman. She is so weak. LMAO. All women do is cry all day, blah blah blah." whut ? I lost many brain cells that day. I always feel like saying "Have you looked at yourself??" but I don't :{ IDK WHAT TO DO as my mother is gravely affected by her behavior.
