I have to tell these girls that eating fake meat is no better than real meat for the environment
Is there something bad about these girls eating fake meat?
Fake meat probably is worse for their health than real meat!
You have this angry thought process about fake meat being no better than real meat, but you have no right to tell others what to do about it. Let those people who want the fake meat eat that, and you eat your real meat. Taking things into your own hands with this will cause so much unnecessary strife and chaos mentally.
Well, I just want to save them from themselves and their bad decisions.
I can understand that you want the best for the girls, but shoving your opinions about fake vs. real meat down their throats and criticizing them is not helpful. Give them the facts about the meat issue and let them decide for themselves instead of trying to "save" them which is really just interference.
