Old friend EA, if you don't have better things to do with your time than criticize my gratitude, then we need to help you find some things of actual (i.e., positive) value.You are interested in philosophy, right? There is no end to what you could read and explore there. I seem to recall also that you have some pretty definite political values--and volunteers are always needed for political causes, as well as for local charities. For that matter, you could also undertake a more personal project--for instance, start a gratitude journal and take stock of the things others have done for you, for which you are grateful.
First, my comment was made in the context of discussing my disapproval with how loyalty to one's side can trump more important values like truth and friendship based on personal character. Your story just served as a ready made example. I wouldn't characterize that as spending my days criticizing your gratitude for being welcomed with open arms and kindness so long as you bow on bended knee to the faith. While you find such behavior at any high investment religion, it's not like I'm dedicating hours each day to critiquing it in your case.
Second, I spend approximately 10 hours a day 5 days a week improving the lives of the developmentally disabled and victims of TBI's. I could easily be doing something that paid more or offered more prestige, but I do not because I care about the cause. I think most people consider that laudable thing to do that falls in line with your condescending advice to find something more valuable and productive with my time to do. On the totem pole of bettering the human condition, I'm fairly certain that ranks well above studying Mormon history. I also am currently working on a political campaign. I also routinely read phil texts. Come to think of it, I'm a pretty busy guy.
Third, this criticism is apt for pretty much anyone since no one divides their time and mental resources to the most efficient way to charitably act. People have hobbies and there's nothing wrong with that. Indeed, people indulging in superficially frivolous hobbies is important to advancing the common welfare as individual pursuit of happiness feeds collective happiness. That one of my hobbies happens to involve posting here and that your name happened to come up was an example in a point I was attempting to make doesn't mean I'm wasting my life way in ungrateful frivolity or lost opportunities for personal betterment.
