Note
Because of you: not 'support' or 'demanding'
Never say support, paying, contributing, supply and demand, or demanding. All give escape routes, someone else creates demand, or they eat leftovers and roadkill. Say: these are your victims.
Gives ammo
You support the industry when you buy meat, you are demanding this.
Gives nothing
As long as you're not vegan, these are your victims.
