Fluid is fine as long as it is used properly.
There are certainly BETTER ways to light your charcoal ... but we chose our techniques and tactics based on personal preference, not herd mentality and cult snobbery.
I personally use chimneys and starter cubes, as it's the most time AND cost effective.
I keep a bottle of fluid around for fun, though. The smells of it burning brings back feelings of nostalgia, and that makes me smile.
