Pretty soon you're the mad bomber and it's far more than local police watching you; you're now a target for Interpol and there are surveillance vans outside your mom's house.
Knowing my luck, I'm already profiled as a loner prone to violent outbursts, even before I got more into chemistry.
But that unfortunately-only-half-joke aside, I get your points. It's just extremists (and their motivations) are usually the last things I'd think about. It's always good to have various points of view, responses like yours are half of the reason why I bothered writing this thing down.
