G'day
sennadog - good question!
In my view, we shouldn't need to
justify ourselves - we should have the freedom to pursue what we want to as long as we don't cause undue harm to others.
Just as those that are passionate about, I don't know: say pigeon racing, love what they do then we too should, within the bounds of civil society, be able to do what we are passionate about - as long as it is legal..!
Of course if, say, a pigoen fancier lived next door to me and his pigeons made too much noise / smell or whatever (the same might go for horses or cars or loud stereos, whatever) then I'd of course expect some constraint and that some moderation, or
abatement, of this behaviour so that my own right to relax in my own home was properly taken into account.
My point however is that, just as those who partake of pigeon fancying, car collection, horse keeping or stereo-playing don't have to
justify their passions/interests, then nor do we. But, like anyone else, we must be "good neighbours", within reason.
If justification is required, then I'd point out the benefits of GA overall, such as the fact that a training infrastructure is required for example. I think we probably do need to get better at articulating this.
If the question is why do we enjoy it, then thats different... and a whole 'nother question
Of course, we love it - or we wouldn't spend so much time nor money on it!
Now: back to work so that I have the means with which to exercise my right to enjoy my passion(s)
Cheers,
(P.S. I see FFF has posted simultaneoulsy - I agree with his articulation, better than mine!)
