Whenever you say you eat meat because you are selfish and weak you are making excuses.
I don't know what you don't undersdtand about that.
You have NEVER made the affirmative statement that you eat meat because your pleasure is more important to you than the suffering your choices cause.
You say I know it's wrong but I do it because I am weak.
Once again that is the very definition of rationalization.
I'll ask again if a child molester told you he rapes kids because he is weak is that not a rationalization?
