It's funny considering how eating meat and using animal products is normalized in society, that when a vegan states a differing opinion (that also happens to be a fact) it's automatically them imposing their beliefs on people. I guess it's a symptom of the omnivore's cognitive dissonance activating for a moment.
Maybe it's stretching the word meaning a bit but I'd definitely be contributing to animal murdering by eating meat. The same applies if I buy new leather shoes. Driving a petrol car, otoh, the connection to animal killing is not as straightforward, but it's harmful for the environment and hence harming wild animals as well.
You can't eat meat without animal murder. It's really that simple. Dragging your fixations on religion into it is just noise and some feeble deliberate attempt to derail the issue and somehow "prove" that you had a point.
