If you think vegans are emotional or angry:
You obviously have never seen the emotional breakdown of a mother cow as her baby is being ripped away from her to be slaughtered. Rather than letting newborn calves live and drink their mother’s milk, dairy farms kill the male calves and grant the female calves the same fate as their mother (forced impregnation over and over until death).
The dairy industry cannot profit from baby bulls (male cows) since they do not produce milk. It is more profitable to slaughter them as newborns rather than let them live.
Like all nearly all mammals, cows only produce milk for their calves. Female cows are forcibly impregnated (raped) by humans with bull semen to start milk production. When their milk production slows, the forced impregnation process starts again. This lasts for about 7 years until the cow dies from exhaustion or is slaughtered for no longer being profitable. This way of living shortens their life to 1/3 of their potential longevity.
