Great mentality.
In the first place, Davin is commenting upon folks suggesting other people who from a safe haven are suggesting others go do some real dirty work. That fits you.
Secondly, all of us have some skills. Your parachute thing, while I might try it if you're buying, is a very big deal to you, but virtually everyone can do something. That you drag it out in this context is the sign of blind, impotent rage.
Third, that is about as childish a comment as I have ever seen an adult put into print. Coupled with the foul language it puts you firmly in the wannabe bully category.
The good news, though, is that I'll bet your mother is proud of you.
Sincerely,
Arf
