You can be against something and still find yourself having to use things you complain about.
Folks still eat food even though they are aghast at how farm workers are exploited in the world.
You can support robust public transportation yet drive a car due to poor-to-no public transit.
Sometimes, facebook is the best place to organize demonstrations against facebook.
Just because you have complaints about the world doesn't mean that you don't live in it and need to use it as designed. If you don't, how else do you expect to change it?
Food itself isn't optional, but folks that aren't absolutely poor generally have choices in which foods they eat.
You can spend more on eggs so the chickens are being treated slightly better.
You can look for meat that isn't produced using confinement farming.
You can buy fair trade coffee.
You can check out how the local grocery store treats its employees, and choose the one with the best treatment. You can try something similar with food producers.
If you have a local butcher, you might consider buying there instead of a factory meat plant.
You can vote for folks that will look out for workers (the ones working the fields and with animals), both in your country and abroad.
Most of these aren't available for folks that are poor enough: You can't very well shop ethically if you are stuck getting food from a food bank, for example, and you might understandably be more worried about getting enough calories for yourself or your child.
