That's great for you. However, animals do not have a voice, despite being intelligent and feeling the same emotions as us.
I am sure if you saw somebody harming a mentally disabled person who could not communicate, you would try to stop them. In the same way, I don't see any harm in being a voice for the animals.
For all we know, in the future we may look back on modern animal agriculture/ factory farming in the same way as we look back on slavery now.
If I can reduce harm in the world to sentient beings at the cost of something tasting slightly different then I will do my best to go down that path personally.
