As with any group, the most unreasonable ones who have a desire to shit on people are often the loudest and get disproportionately more attention.
That's the same dynamic why conservatives think feminists hate men, for example. It doesn't mean it's representative.
Most vegans have been meat eaters for most of their life and didn't went vegan overnight either. Many also recognize that going 100% vegan can seem very daunting to people who have never tried being vegetarian for a week or something like that yet. It certainly seemed daunting to me at first.
I now wish we could stop all factory farming today, but that's not how human psychology works, and it's not how societal change works. Some vegans aren't emotionally able to accept that, but most probably will at some point.
The main struggle for the accessibility of vegan food is having more plant-based options in supermarkets and restaurants, and more people who are trying/choosing the alternatives (when they are available and decent) would go a long way to make it easier for all. So I'd always encourage people to take steps to improve the situation.
The "all or nothing" mentality just creates unnecessary barriers and some people really need to recognize that. People have to be able to take positive steps without feeling the need to make a big commitment.
I feel like this is insanely hard to do this right, since the treatment of the animals is never made transparent. Even if you only buy animal products from local farms, how do you know the actual living conditions? You'd have to visit the farms and the slaughterhouses yourself, and even then you wouldn't see all the stuff, like how the workers really treat the animals day to day and which procedures the animals go through, how they are separated after birth and so on. To get a fair, unbiased impression, you'd need to work there for some time, for every farm you buy from.
For food from normal restaurants (which aren't $100 per meal), the employees have no idea where the animal products come from, and if they have to compete with the prices of other restaurants, well, it's all factory farmed anyway or they would already be out of business.
Just buying the plant-based burger or whatever is just so much more practical than trying to be a conscientious meat eater in a world where you're not supposed to ask any questions about how products were made. If you try to get some real transparency, the odds are stacked against you, and the industry will make sure to keep it that way. They'll just push for some labels that make people feel good and that can be used for marketing, but don't actually tell you much, and they know that's good enough for most people.
