You now have to argue that oxidative stress isn’t suffering. Biology does not allow for humans to divide the world into the regions where suffering can be experienced and regions where it is absent. (The other branch contradicts the lived experience of anybody who has actually raised a sourdough starter; it is a living thing which requires food, water, and other care to remain homeostatic, and which changes in flavor due to environmental stress.)

Worse, your framing fails to meet one of the oldest objections to Singer’s position, one which I still consider a knockout: you aren’t going to convince the cats to stop eating intelligent mammals, and evidence suggests that cats suffer when force-fed a vegan diet.

When you come to Debate Club, make sure that your arguments are actually well-lubed and won’t squeak when you swing them. You’ve tried to clumsily replay Singer’s arguments without understanding their issues and how rhetoric has evolved since then. I would suggest watching some old George Carlin reruns; the man was a powerhouse of rhetoric.
