Wait aren't vegetarians and vegans on the same side?

Vegetarianism is a dietary choice where one does not consume animal flesh. Veganism, on the other hand, is an ethical principle against animal exploitation. There is very little overlap to be made with these two definitions.

If vegans unconditionally oppose animal exploitation, vegetarians refusing to engage in just one kind of animal exploitation (which could be for literally any reason, mind you) are very overtly not in alignment with the vegan movement.

IMO, many things are unethical and you cannot stop eating anything. If you buy pizza, there is cheese. If you buy chips, there is also a little dairy for some reason. Its impossible to stop 100% sadly.

This is a major stretch! There are literally so many ways you can eat and live without supporting animal exploitation. You're cherry picking here, to be honest, basically saying, "Cheese pizza is common, and there is milk powder in some potato chips, so therefore, it is impossible for vegans to live without consuming dairy." Once you understand the "why," the "how" becomes easy, and even for someone who isn't a vegan, but, let's just give an example, a person with a very severe dairy allergy, avoiding cheese pizza and chips with milk powder in them isn't really even among the most difficult obstacles they'd face.

Its impossible to stop 100% sadly. Sometimes you must just do what you can

This is an appeal to futility that you're using to justify your very defeatist mindset.

Sometimes you must just do what you can. Because things can make a difference.

And people easily can avoid cheese pizza and chips with milk powder in them. People easily can live in alignment with the vegan principle because, like I said, once you understand the "why," the "how" becomes easy.

If vegetarians and vegans dont stand togheter, i see no point in changing the course of the murder factories.

"If transphobes and trans allies don't stand together, I see no point in changing the course of trans acceptance."

This statement is equally as sensible.

Remember, i fully support veganism and i acknowledge you do a lot for animal rights.
