funny thing is this doesnt quite say what you think, it highlights the preachy message. the fast food ads have a picture, a slogan, thats it. the vegan is wordy and telling you what to do.
as to the OP, seems to me the sensible approach is to decide to cut out meat and maybe meat products when convienent. making your self a slave to the alter of veganism is daft, having to constantly check if food is suitable, buying more expensive food to meat a self imposed dietry regime.
I know what you mean but why do people feel the need to but expensive substitute products? Veg is cheaper than meat.
