We don't get to say "Yeah, but my personally not participating won't change anything," and wipe our hands of it.
With respect to your own journey, perhaps this will help you to fully embody. Myself for years brushed off all the standard vegan debate bro arguments for veganism.
Like, sure, yes, it's bad to eat animals, for any number of reasons, without even asking the question of how it impacts the animals themselves. Enlightened self-interest alone, as inhabitants of a planet being rapidly changed, in significant part, by industrial animal husbandry, should be reason enough to not participate in those systems.
But as someone who lives subject to those systems, it would just be more difficult to not eat animals or animal by-products. It would require more thought and effort on my part. And that was where my engagement with the issue ended.
Then 2020 happened, and we learned that chains of transmission, however many steps removed, can kill or disable people we don't even know.
