This is in general, not directed to anybody specific.
I don't get it: you want to give blood, they have a reason to refuse it. SO WHAT?? Are you going to get sick because they refused you? Is your life going to be less full and complete without giving blood? Are you going to go in a deep depression if you're not allowed to give blood? If any of these are true, you have a way bigger problem than being refused as a blood donor.
All I see is a revolt against the system, nothing more! And a useless, pointless revolt too! You want to give blood, you're rejected and you take it personally. Guess what? It's nothing personnal!! YOU could be safer than all the other donors, tatooed, hobbyist and all but, what about others who aren't as clean as you? Hema Québec have to draw a line and that line can't be crossed. It might bruise your ego but, that's a minor problem compared to somebody being infected/killed by bad blood. It's a restriction we, as a society, must accept, without seeing it as a personnal attack.
A friend of mine almost died because a donor had peanut butter and, of all the bags he could have gotten, that's the one he ended up with. Problem is, he's allergic to peanuts! That's only peanut, right? Not Hepatitis, not AIDS, only peanuts. But nearly deadly for him. ANY PATHOGEN can be deadly to somebody who's already sick. ANY INFECTION can do the same.
Hepatitis, doesn't this ring a bell? Few years ago... Still paying for it. Will they make a similar mistake again? NO WAY!
As far as lying, of course you can! But, what if you discover your "pure" blood is in fact infected, a few month down the block, without your tests showing anything at the time you donated? Could you live with this, knowing you might have infected/killed others? How futile your revolt will look like then?
Personally, I prefer they err on the safe side rather than being permissive. Are they filtering 100% of possible problem-donor with these methods? No kidding, probably a lot is going tru! But if they filter 2%, even 1%, even less than that, that's that much less chances I risk someday getting the blood of an infected donor who would have been accepted without these measures.
I don't know about you but, if I play Russian Roulette, I prefer 1 bullet in the 1,000,000 shot magazine anytime over 2 bullets in the same one.
