Earlier quoted context omitted.
Your ability to eat as much food as you desire is synonymous with living in a first world country. The ability murder as many animals as you want is not the desired state I look for when thinking about the world in which my child to grow up. A future in which that is synonymous with status is backwards - to me.
Well, you can choose to not contribute to animal-based agriculture. Similarly, I do not want mine to grow up in a world with forced veganism. Who wins in this conflict? I would say you keep your morals in your court for such contentious issues, to do otherwise is maliciously aggressive.
That said, I invite you to consider what you would and would not allow others to do given a hypothetical: if you genuinely believed that cows were just as capable of suffering as humans — especially given that cows lactate only after giving birth, and dairy cows live only for so long as their milk is worth more than the cost of keeping them alive.
Most functioning adults can keep quiet about a simple preference (for Star Trek when around Star Wars fans, or whatever) but morals don’t work the same.
