Why are women saying their rights have been stripped away today? (i need context plz)

for context i’m not heavy into politics and this question is literally for curiosity purposes. all over my facebook today i have been seeing SOOO many posts containing phrases similar to “my rights as a women have been stripped away today” & “women are not even human being anymore they are property now that trump is in office”. IM CONFUSED because he isn’t even in office yet so like how are women’s rights stripped away all of a sudden today when he is not in office yet? also i’d like more context on why so many women feel the need to act so scared when he has no power currently. is he planning something i have not seen? if so what is it and is it valid? i just want to learn, plz help. - a woman :) (also i didn’t vote this year ik shame me i suck) ((delete if not allowed))
