I wouldn't let a few idiots worry you and stand in the way of you doing what you enjoy and what you are good at,Sod'em, for every one fool who makes you think twice,think of the many who you've helped and the wonderful times you've given to people through your mods and with your work with GWX
I find alot of carping comes from jealousy and ignorance,remember its easy to be destructive,any fool can do that,but it takes genuine talent to be creative
and if thats a problem for them then tuff,sod'em
