It happens to vegans, too. There was recently a campaign against soy milk, because cows can eat grass and grass is better than soy on certain metrics. That much, alone, is true. But if you're drinking equal volumes of soy milk and dairy milk, dairy is worse on every metric but price - Animal cruelty, health, clean water polluted, space needed, energy needed, carbon and other air pollutants released, etc. I can't speak for the UK where the campaign was, but in the US the cheap dairy milk is probably not coming from grass-fed cows. The cheap milk is coming from factory-farmed cows that are probably eating lots of soy, and then the government also subsidizes it to drive down the cost in a misguided attempt to give poor people cheaper food without giving them any agency in their decision-making like an actual welfare program would. (I'm upset about this) To further muddy the waters, some of the Amazon rainforest fires were started to clear land to grow soybeans - To feed to cattle.
