Was I wrong to tell Climate Activist neighbour that that she should lose weight to save the environment?

She was criticising my family's carbon footprint and how we don't have an electric car and basically compared us to the nazis and I responded that she has a far higher carbon footprint. She asked how and I pointed out that because she is obese she eats 4 times as much food which uses 4 times the carbon to transport and grow, she requires 5 times the fabric to cloth herself which requires more carbon to make, grow and transport. That she weighs more so any transport she uses requires 4 times the energy to move her. She takes up two seats on planes and trains. Her weight causes more wear and tear on vehicles, so it does. I could have gone on about how her weight drives up the cost of healthcare and health insurance.

I thought she was going to hit me but she walked away with a face like a bulldog. My partner said that it was a little mean but she came over to our front garden to gave me a piece of her mind. Good for her protesting about climate change every weekend.
