Ok first of all you should be able to conduct your peaceful hobby without the fear of molestation from slack-jawed yokels, white supremacists etc. Secondly, no one should loose a loved one due to the actions and hatred of another.
That said, why would you take up fishing as a hobby when you can not swim? This seems foolish unless you have hired a nice young man to run your baited hook from your rod, held safely in your hands while you sit inside your car, to the lake to fish. Unless this is an extreme sport that I am unfamiliar with it seems like a slightly foolish risk (Can you say shark repellant tester?). Even if you remove the possibility of roaming gangs of “pushy” thugs, any unfortunate calamity would involve drowning (gust of wind, too much beer, dropping the bait bucket). The proper selection of this hobby should involve the distancing from water rather than a friendly hug of aquatic citizens. This pairing of personal skills and hobby is equivalent to a: claustrophobic spelunker, a mountain climber with a fear of heights, a blind stunt pilot, a motion sick NASCAR driver or a diabetic confectioner. Please people think ahead.
