Is it 100% optional? Are there no dietary conditions that require eating meat? Even if it is optional, I only said that expecting everyone to change is unrealistic, not that it’s impossible.
How much do you expect people to sacrifice? If you give up eating meat can you fly to go on vacation? Or are people expected to give up everything in the name of the climate while billionaires jet around and corporations expell endless emissions?
Also, your comparison to mercenaries is bad. If military operations are required for survival (like eating) then why would the nation feel guilty? If the mercenaries say “yes we will only defend that military base and we will not kill everyone in the nearby school” and then they go and kill everyone in the school, why wouldn’t they be blamed for not following their orders?
I mean, many (several?) sites tried optional subscriptions where you pay to get rid of ads, but that doesn’t seem to have worked. Judging by the fact that most sites that have subscriptions instead of ads use pay walls.
People have come to expect free access, so if you can easily use an ad blocker, why would you choose to pay to remove the ads that a blocker removes for free.
