Through that meat industry though there are huge financial subsidies on meat products such that eating dirt-cheap meat is often more affordable, huge advertisement campaigns resulting in personal and social pressures to consume meat, meat becoming commonly understood to be a default staple in meals through the industry's influence on nutrition education, eating vegetarian or vegan at a restaurant/conference/meeting etc. having severely limited options, etc. etc.

There are far more external factors prompting your consumption of meat than beating your spouse. I agree that veganism is a crucial part of liberation, but you can't expect all comrades to be perfect - they still operate within the confines of capitalism, much like the climate activist with a car. Yes I know driving a car is different to eating animal bodies, but lot of ideological work has been done to separate consumption of meat from the consumption of corpses harvested through mechanized genocide.

Some comrades will come early to this mindset, some late, but you can't dismiss people who are clearly trying to understand liberation for not being perfect instruments of it, they're still learning and they always will be, and they're on the right path too. Help them.
