I don't really understand this.. Worth of what? Your efort? Time?

Anyway I guess it depends of situation, you can probably never change other person views in some simple debate, you can however, by backing your claims, providing arguments, etc. strenghten the views of other people who have simmilar beliefs and happen to be listening/reading to what you're debating. For example, you see on internet or you listen in real life to some debate and you can always learn different things from people with simmilar views like yours, see what kind of arguments they use etc. Usualy I don't even bother with other people, I do that for myself and people with simmilar ideology.
