In regards to spreading Windows viruses yeah I feel bad for Windows users but I won't spend my own money and processor cycles on worrying about their systems. If they want to protect their systems then they should take steps to protect themselves. They could also dump Windows and get an operating system that isn't so ridden with viruses and malware. That's their own choice and problem, not mine.
My thoughts exactly. It should be up to everyone else to protect themselves so that I'm protected by virtue of their diligence.
I mean, I don't wear condoms because everyone else has been told to protect themselves with birth control and prophylactics. I have nothing to worry about, right?
An Ada exception is when a routine gets in trouble and says 'Beam me up, Scotty'.
