I would argue that no, it is not morally wrong per se to be non-vegetarian. Meat consumption is not morally wrong in general, it is just morally wrong in our society. We kill way too many animals to be sustainable and every animal you eat contributes to that. We harm climate and ecosystems to sustain our meat consumption. We hold animals captive and make them hurt and suffer. In this society you can not eat meat in a morally okay way.
