Weak
Do you believe humans should respect other animals?
Strong
Do you agree that humans should respect other animals?
Do not call them a hypocrite from line one, and do not rush to label them. Ask step 3 clearly so they conclude that respect and exploitation cannot coexist. Sometimes we give them the answer too quickly instead of letting them say it.
Weak
You're a hypocrite because you're not vegan.
Strong
Can you truly respect other animals if you use them for your purposes?
Do not open with veganism being healthy or good for the planet. When asked the biggest advantage, justice and ending hypocrisy, not health. Only address health if they raise it genuinely.
