Well, if that was my normal experience every time, I might wonder if I want to fly too. I fly a lot and I'm a tall, blonde, Nordic looking fellow and I get pulled aside for extra security (body wand) a good 80% of the time I go through security (whether I set off the detector or not). They swab my carry-on for explosives (usually in a separate room, depending on airport) etc about 50% of the time.
100% of the time, this has happened in US airports, not EU airports and I've flown through most all the major ones from Munich to Helsinki. This is all since 9-11.
I've not though been made to feel like a criminal. Most TSA agents do seem pretty dense and I've been questioned as to why I've been to Estonia (then they ask me where it is). I look at TSA agents as people that had their application turned down at Walmart. I assume (and by the demeanor of the TSA) believe I'm the guy they screen because I'm the opposite of a terrorist. I'm the token white guy they have to screen so they don't get blamed for racial profiling.
Personally I wouldn't cancel a trip over it. I love to travel and as they say, getting there is part of the adventure. I try to look at airports/security/etc as part of the adventure and not stress about it. I always arrive to airports early (my nature, I'm early to everything).
But Zero, if they make you feel like a criminal and threaten you every time you fly, then I do understand you wanting to spend your time locally.
