yea, seems a little wack. you should do what you think is right in this case, even if you don't think it's going to make a huge impact. maybe it will make a difference, maybe it won't, but that should be secondary to doing what you feel is right and good. this example just sounds like an excuse to not follow through on your convictions... or maybe you don't care enough, which is fine, but there's no need to lie to yourself/others about it
