I personally feel that convenience and personal taste is less important than the suffering of billions of animals. Your personal taste has a small impact on the total suffering, of course, but the sum of meat eaters taken together creates the demand that necessitates factory farming.

If you voluntarily consume meat given the means of accessing the alternatives, then I say the choice is not ethical. How you or anyone else personally weighs that choice against other concerns is up to you. I'm posting this from a phone more than likely made by children working untenable hours. When I discard it, it'll likely pollute a poor country. I know we have to pick our battles, so again, no judgement. I do like to discuss these things though! :)
