Please learn a bit about the incidence of taxation: https://stantcheva.scholars.harvard.edu/sites/g/files/omnuum... The main models supporting your view is where consumer income is exogenous and all firm profits are redistributed to the representative consumer as a lump sum transfer: https://www.ief.es/docs/destacados/publicaciones/revistas/hp...
Please avoid simplistic beliefs and moral outrage for things as complex as trade policy. The people who say that the incidence of taxation falls heavily on sellers may just be better informed, particularly when listening to wall street earnings calls while simultaneously looking at the consumer price data.
