The merit in clarity and precision has less to do with your particular occupation or averageness and more to do with raising the floor for intelligent discussion upwards.

One of the things we debate as a society is taxes, because we live with them, pay them and discuss the services and salaries these taxes pay for. It is therefore incumbent upon participants to put their best foot forward in the larger discussion, and equating avoidance with evasion mimics vapid and hollow rhetoric. Else why bother to participate?

It is fair to criticize IKEA and you can certainly stake out a position as an adversary to their tax avoidance scheme without equating it with tax evasion out of a sort of intellectual laziness for one is within the realm of legislative discretion and the other within the real prosecutorial discretion and lead to two entirely different discussions.
