Answer

I didn’t understand why the identification is with “secular people.” It’s with the animals, isn’t it? Do religious people not care about their suffering?
Some wanted to say that in the future, the sacrifices will be abolished (Rav Kook, in light of several midrashim), because when the world is repaired enough there will be no need to cause suffering to animals. At most, offerings from plant life will be brought (meal-offerings). He writes that then there will also be an obligation to be vegetarian (I think even vegan). Although I assume this will no longer be necessary, since we are approaching the industrial ability to produce meat and dairy products synthetically (without raising animals and causing them suffering).
By the way, let me ask whether you, as someone who identifies with animal suffering, refrain from eating meat and dairy products. That can already be done today. I ask because many of us have a tendency to wonder about the Torah and Jewish law, but not to take action where we actually can.
By the way, the actual offering does not cause great pain and suffering. The main pain and suffering is not in the killing but in the raising. Eating, which is widespread and requires industrial, large-scale animal farming, causes far more pain and suffering than offering sacrifices.

Questioner:
You’re right. For the sake of fairness, I wanted to write at the start that I am not a vegetarian, but in my opinion that doesn’t matter all that much, because my question is about the Torah as a divine and eternal source that claims that the ideal is the offering of sacrifices—and not about me as a private individual who is still given over to his craving for meat…
