It's not really an answer, it's a lazy holier than thou cop out. Expecting the general population to get on board with veganism is arrogant and a waste of time. It's a fight that you're never gonna win and is just gonna piss people off.

You wanna know how you reduce the reliance on factory farming? You work with people to come up with solutions that are slow and sustainable. Meatless Mondays to start, then maybe you do one week out of a month.

Also veganism is unnecessary - vegetarian is just as effective and it accepts that animals are going to be a part of human diet from time to time. We're omnivores we're gonna eat animals and animal byproducts. It's just a fact of life and trying to tell billions of people that they're wrong for eating meat or cheese or gelatin is just just about the most arrogant bullshit out there.
