First of all, whether something is "sentient" is a bit subjective, and whether eating a sentient being is okay is also quite subjective. If we strike that list item, we are left with the climate change argument. However, they're also missing a number of other arguments, such as: - difficulty eating a balanced diet - inconveniencing others (must take into account vegan options when going out to eat with coworkers/clients) - some meat sources don't particularly contribute to climate change (e.g. hunting/fishing on your own) If your going to try to come up with a deductive argument in support of veganism, you need to take into account all major arguments on all sides of the issue (vegetarianism, piscatarianism, etc). As such, I'll only accept this argument as a completely subjective argument because the climate change argument (and part of the sentience argument) entirely depends on how you source your meat, leaving the completely subjective sentience argument.
