My fiance of one month labeled me a patriarchal chauvinist for supporting Atul Subhash on social media.

I'm engaged to a girl who matches a lot with what I have always dreamed of, beautiful, highly educated, professionally successful. We met via a matrimonial site and liked each other from the very first meeting, though I don't know much about her and her family otherwise. Yesterday, she found me supporting Atul Subhash on social media, took a screenshot of my activity and Whatsapp me, saying she never thought I would be one of those "rowdy guys". I thought she didn't know about the case, so I explained the whole situation to her. She asked me not to be so naive as to trust social media and that there are always two sides to every story. I didn't feel like discussing anything further, it was just tiring. Today, since the afternoon, she has been constantly labeling me as anti-women, anti-feminist, and a patriarchal chauvinist. She said even her mom is not happy with me on this. I can't understand her aggression. I was really happy and excited since we got engaged in November. I even agreed for simple wedding that she wants and make all arrangement on my own so that there is no load on her father. I am an introvert who mostly keeps to myself and is not very good with words, but I don't remember anyone belittling me like this in my life.
