Football coach sexist or nah?

Basically I play flag football for my city (rep) and I wanted to try out for my schools team the coach said there's no team for the girls I told him thats fine I can play tackle too. He asked me "Do you know what tackle is" Im like bruh i know I've played tackle as well. He asked what position I play and I play running back i told him and he said to come to the try outs and WATCH i said hell nah imma play... He told me that there's gon be 300 lbs guys out there trying to knock you out but I told him ill knock them out before that happens... Is he sexist jus cuz im a 15 year old 100 pound 5'2 girl
