The wearing of perfume is an arbitrary choice, it's not a necessity, and if your co-worker is rendered physically ill by your wearing it to work it's reasonable that you stop wearing it.
Not if my anxiety about smelling bad makes me sick. Often it's merely a question of "My neurosis trumps your neurosis."
Or, alternatively, it's reasonable for you to find another job where you're not exposed to your fixation. It's a matter of perspective.
If you were suffering from emphysema and carried an oxygen tank around and, I as you co-worker, came in every day and blew cigarette smoke all around and stank up the office don't you think you would get ticked?
I never acknowledge silly hypotheticals. That's posturing, not argument.
And a smoker could claim a better argument than the perfume wearer, smoking is an addition, perfume wearing is not.
Again, that varies among individuals. It could be a physical as well as a psychological addiction. Your mileage may vary.
Coercion by the state, who employs armed goons who "just follow orders", is the problem.
What???? “My neurosis trumps your neurosis”
A neurosis and an allergic reaction are not at all the same thing. While a neurosis might make you uncomfortable, an allergic reaction can stop your ability to breathe.
“The problem starts when things like the ADA abomination becomes law, and it’s no longer a matter of choice”
Making the choice to inhale toxic materials is definately up to each individual; forcing others to is not.
