I have absolutely NO CLUE as to why anyone would think that someone else whom uses their religion/faith as a means to curb something very negative in their life is a "bad" thing
Whether anyone else "believes" or not is none of my concern. But if said belief gives them a sort of "power" and helps them to overcome their negative(s) (In Josh's case, severe drug-addiction), and said belief(s) are not hurting anyone else, how in this great big ole world is that a BAD thing AT ALL? Man, I just can not understand that line of thinking personally.
I'm FAR from the biggest proponent of organized religion, but I have seen, time and time again, many people use it as their way of dealing with and overcoming drug addiction issues as well as a whole array of other negative things they had in their lives (sometimes things that have had NOTHING to do w/drug addiction or the like whatsoever). Just exactly how this translates to a BAD thing, I'm not exactly comprehending here.
Can "over-doing" (so-to-speak) one's "religious zealousness" BE a negative thing? Sure. But in this particular case (Hamilton's drug issues) and in many other cases in which people whom find religion become better people and attribute said positive changes in at least part/some form to said religion/faith, then I find that a very positive thing.
Strictly in reference to drug-addiction, some folks find that a trip or two (or more) to rehabilitation clinics/programs does the trick. Or counseling. Some people simply have amazing willpower. Others find and attribute their sobriety to their faith (religiously speaking). Addiction is a VERY EVIL beast and it is one for those whom suffer from it in which a "not-one-size-fits-all", so to speak, method(s) will work. Some people find sobriety while NEVER simultaneously "finding" or "turning to" religion. Others who choose to turn towards religious belief and faith sometimes find that that does the trick.
Bottom line here: whatever gets Josh Hamilton through another sober day and helps him keep those personal demons of his at bay while simultaneously not causing any harm whatsoever to anyone else is nothing but an absolute POSITIVE thing in my personal book of belief. I simply find it difficult to comprehend that anyone could see it, especially in this particular example, in any other way.
