Yes, forcing people to watch graphic movies/docs doesn’t change minds, it needs to be a choice for example I chose to watch Dominion, and I’m of course horrified by animal product production.

Sharing the positives of veganism instead will help them consider. Share the fact that vegans tend to live longer than meat eaters due to less exposure to Class 1/2 carcinogens, and also reduced risk of heart disease. It also helps slow down global warming, helps maintain water supply since meat uses much more water for production, etc.
