As I often see, people that don't get out of their own little niche often don't understand what life is like beyond that. They make judgments from a limited amount of knowledge so I see that in play.
Also, this website spans living situations and locations. Everyone won't be living in a van, jobless, etc. as they are here looking for advice on a best fit for them. I don't know about everyone else but I don't share a lot of financial info on the web or other personal details which when left out might make my decisions look like less than something to be desired. I'd have to write a book to cover everything. So we are always working with limited information about an individual and making judgments in that case leaves much to be desired.
I think you can't really comment on where I am going if you don't really understand where I am at. When people ask specifically if someone thinks something is possible, there are kind ways to direct that person to think it through for themselves and that is what I try to do. Give them the resources to use to make the decisions that will work for them.
I saw a budget on another website. It was judged and ripped apart by some. I was very annoyed. Show me your budget and I won't criticize how you spend your money, I will use it as a template. You spend $40.00 a month on eating out? Well, I don't eat out but I buy dog food so I substitute that expense in the eating out category rather than talk about what a waste of money is eating out, then I get judged for "wasting" money on my dogs.
I often see a lot of hostile posts in blogs being critical of the ideas, thoughts and actions. The bloggers put so much time and effort in doing this. You simply take what you can use from the information and leave the rest.
