Here is the thing, if the majority of society says it is porn, and if the court in your nation says it is illegal, then that's all that counts eh.
Because being obstinate, and refusing to bend, might only end up with you in jail. And then you have to ask yourself if your opinion on the matter was truly worth it.
And that's really what it's about eh, is it really worth it?
Always remember to pick your battles wisely, because it's your life you might be screwing around with.
And is your personal freedom worth enough to you, that you can be forced to find something else to draw.
The people on the internet, that like to merrily play with themselves looking at art that might in some nations be considered criminal, won't shed a tear if you get arrested. They'll just move on to the next artist.
It's like piracy, I didn't care when they crushed Napster, didn't care when Supernova was destroyed, was not surprised that Piratebay eventually was defeated and I know that Mininova won't be the last victim. There will be others, and I just move on.
I think loli is images under 13, NOT images depicting people over 12. And that is ONLY an opinion, and no basis to risk one's freedom over. I also think images have NO age, and that art is not really different that a photo of a person.
An image of Lumière of the series Kiddy Grade for instance. Looks like loli, and a judge not having seen the show might treat her as a child, and I would gladly state matter of factly, 'your honour, she's old enough to be your grand mother, so cut the loli crap out'.
How old are images really? Are they as old as they are from the point of creation? ie if drawn 5 years ago they are 5 years old? These 'persons' never breathed, never existed. They are not some individual which is being written about that previously lived either (unless that is specifically stipulated ie a drawing of a real person from their youth).
My only objection to loli, that is under 13, where the image IS an image of a person that IS under 13, is I find people masturbating thinking of having sex with the individual is undesirable. And the undesirability escalates rapidly the younger the image gets. Past 10 and the disgust likely reaches critical mass to the point it no longer matters how much further you go.
But that's all just opinion eh.
And my opinion appears to have no relevance to Canadian criminal law.
Wanting to draw loli, even if you are indeed a properly trained artist, is what it is. It's an admission you find loli interesting. And you have to expect it will be given the reaction you should expect it to generate.
You might as well admit to finding sex with corpses fascinating.
