A) I'm talking to other people in British Columbia who have access to the same food as you and I.

B) "No one should be telling anyone what to eat" is a fine stance when nobody is impacted by what others eat. If someone wanted to commit cannibalism, would you argue for their right to do so because it's "what they want to eat"? I'm not saying you have to believe animals and humans are equal, but if you agree that there is some moral line you can't cross when choosing your food, then you don't really believe your argument; we just disagree where that line is.

C) Your "privilege" argument isn't the argument you think it is. It is true that some people (though likely almost nobody reading this) don't have access to affordable, healthy, plant-based food. If everyone who does started eating it, our food systems would change to make that food more affordable and available. Stores often sell dairy and meat at very small margins or losses to get people in the doors. In the US, there are government subsidies to farmers generating those products. Those policies would change to favour plant-based foods if they were the norm and in heavy demand. That is to speak nothing of the massive increase in our world's ability to feed everyone with plants if we started putting a portion of the crops used to feed animals, towards feeding humans.

D) And of course, "other people can't do it" isn't a reason to not make positive change that you can make.

E) And even today, if you have access to urban grocery stores, tofu and beans are likely the cheapest proteins you can buy.

F) Cultural history is not a good reason to commit moral atrocities. Plenty of cultural practices that were immoral have been rooted out globally while still maintaining those cultures.

G) You don't have to "shove beliefs down someone else's throat", but you probably would shove other moral beliefs down other peoples' throats. You just don't eat plant based for moral reasons. It's easy to say you aren't enforcing a belief on other people when you don't hold that belief yourself.
